1 | Brand Overview — Why UGG Matters

UGG began as a post-surf comfort solution and evolved into a global symbol of self-expression: comfort engineered into culture. The brand narrative combines California heritage, everyday luxury, and a modern stance on inclusivity and responsibility.

Today UGG spans classic sheepskin boots, slippers, clogs, platforms, waterproof boots, apparel, and accessories — with a design language that pairs softness, warmth, and lightness with real-world durability.

What UGG stands for:

  • Comfort as identity: Softness, lightness, warmth — but also confidence and ease.
  • California heritage: Surf origins → Hollywood adoption → global mainstream.
  • Progressive culture: Collaborations, celebrity adoption, inclusive community.
  • Responsible intent: Materials and manufacturing choices that move toward lower impact.

OD's take: We stock UGG because it serves real British life — school runs, stadium steps, city commutes, and winter Sundays. It's luxury you use daily.

2 | Craftsmanship & Materials — What's Inside the Comfort

UGG's comfort is material science plus disciplined construction.

Core Materials

Twinface Sheepskin

A single piece where suede is the outer face and fleece is the lining — naturally breathable, moisture-wicking, thermoregulating. Breaks in to the wearer's foot for a custom feel.

UGGplush™

A soft, durable lining that blends 80% upcycled wool with 20% lyocell to mimic the feel of sheepskin while improving consistency and longevity across styles.

Premium Suede & Leather

Often pre-treated for water resistance on Classics; responsive to regular care and protection.

Outsoles

EVA, Treadlite by UGG®, and SugarSole™ (a renewable, sugarcane-based EVA). These platforms reduce weight and increase flexibility and rebound.

Construction Highlights

  • Lasting & Stitching: Balanced to reduce hotspots; double-stitched stress zones on key silhouettes (Classics, Neumel).
  • Toe & Heel Structure: Soft support that holds shape without hard edges; platform variants use reinforced boards for stability.
  • Waterproof Builds: Fully sealed seams, waterproof membranes, and specific leathers (on designated waterproof models) — distinct from water-resistant Classics.

Fit behaviour: Sheepskin and UGGplush compress slightly with wear; liners bed-in, not "stretch out" dramatically. Start true-to-size unless you sit exactly between sizes.

3 | Innovation — Lightness, Longevity, Lower Impact

UGG's technical platform focuses on weight, comfort, and materials evolution.

  • Treadlite by UGG®: Lightweight, cushioned outsole compound with high flexibility and grip for daily wear.
  • SugarSole™: Sugarcane-based EVA that replaces portions of fossil fuel-derived EVA.
  • UGGplush™: Upcycled wool + lyocell lining engineered for consistent feel and fewer raw-material constraints.
  • Waterproof Engineering: Purpose-built membranes, taped seams, and treated leathers on fully waterproof ranges (distinct from Classics' water resistance).
  • UGGRenew: Refurbishment support — clean, condition, sometimes repair/restore select styles to extend life (availability varies by region — check UGG official site).

OD's point: Comfort is now a system — upper, lining, and sole technologies tuned for all-day use.

4 | Culture, Collaborations & Celebrity — From Malibu to Manchester

Cultural Arc

  • 2000s Hollywood Boom: Oprah's "Favorite Things" moment plus pervasive off-duty celebrity adoption transformed UGG from surf staple to lifestyle icon.
  • 2010s Mainstream Luxury: Supermodels and everyday styling cemented Classics, Minis, and slippers as global uniforms.
  • 2020s Streetwear & Designer Crossovers: AMBUSH, Palace, Telfar, Gallery Dept, Collina Strada, Reese Cooper, and more — pushing platforms, clogs, and gender-fluid silhouettes into new scenes.
  • UK Present: Central Cee and the Gen-Z streetwear lens made platforms and minis part of British everyday style.

Why This Matters

  • Validates price and longevity: these products live beyond trends.
  • Gives styling permission: joggers, denim, tailoring, dresses — UGG crosses categories effortlessly.
  • Fuels content: every season brings new looks for email, blog, and social.

OD's edit: We translate global hype into real UK outfits — pairing Classics with parkas, puffers, trench coats, and knitwear; Tasmans with cargos and overshirts; platforms with wide-leg denim and tailored coats.

5 | Sizing Hub — Find Your Perfect Fit

Last Updated: October 2025

The Essential Rules (Start Here)

  • UGG runs true to size across most styles
  • Linings compress slightly with wear for a snug-to-custom fit
  • Between sizes? Choose based on sock plan and desired snugness
  • First wear feels snug? That's normal — liners bed in within 2-3 wears

Quick Fit Guide by Silhouette

Style Type Sizing Advice Sock Consideration
Classics / Minis / Ultra Minis True to size. Expect snug initially, then quick break-in. Barefoot or thin socks: TTS. Thick winter socks: half-size up where available.
Tasman / Slippers True to size. Enclosed heel keeps them secure. If wearing thick socks regularly, consider half-size up.
Platforms True to size. Stable footbed, minimal extra length needed. Standard socks work perfectly at TTS.
Waterproof Boots True to size. Factor in winter/thermal socks if needed. Heavy winter socks: consider going up half a size.

How to Measure Your Foot

Method 1: Paper & Ruler (Most Accurate)

  1. Place heel against a wall on a flat piece of paper
  2. Mark your longest toe
  3. Measure heel-to-toe length in inches
  4. Match to the conversion tables below

Method 2: Existing Shoe Check

  1. Check the size of a well-fitting shoe in UK sizing
  2. Use that as your starting point
  3. Consider whether you want the same fit or snugger/roomier

Pro tip: Measure in the evening when feet are slightly larger. Measure both feet and use the larger measurement.

Important Kids Sizing Notes:

  • Ages are approximate — always measure foot length
  • Kids' feet grow ~1–2 sizes per year (faster when younger)
  • Allow ~0.5–0.7cm (¼ inch) growth room maximum
  • Check fit every 2–3 months for active growth periods
  • Too much room = heel lift and reduced warmth
  • If approaching UK 6, transition to adult women's sizing for better selection

6 | Care, Cleaning & Aftercare — Keep Them Looking New

UGG-Specific Care — The Golden Rules

❌ NEVER:

  • Machine wash or dry-clean (voids warranty and destroys materials)
  • Use direct heat sources (radiators, hairdryers, sunlight)
  • Soak completely in water
  • Use harsh chemicals or bleach

✅ ALWAYS:

  • Protect before first wear with UGG Protector Spray
  • Spot clean immediately when spills happen
  • Air-dry naturally away from heat
  • Re-apply protector every 2-3 months

Care by Material Type

Suede & Sheepskin (Classics, Minis)

  1. Apply Protector Spray before first wear
  2. For dry dirt: Let dry completely, then brush with suede brush in one direction
  3. For wet stains: Blot immediately with clean cloth. Dab (don't rub) with cold water. Let air-dry.
  4. For oil/grease: Use UGG Cleaner & Conditioner; follow kit instructions
  5. Refresh regularly with suede brush to revive nap

Leather Styles

  • Use dedicated Leather Care Kit
  • Clean with damp cloth; condition monthly
  • Buff with soft cloth for shine

Fluff / Sheepskin Uppers (Fluff Yeah, etc.)

  • Spot clean gently with cold water
  • Pat (don't rub) with clean towel
  • Air-dry in cool, airy space
  • Avoid heat — it damages fleece structure

Waterproof Styles

  • Wipe clean with damp cloth after muddy wear
  • Re-apply waterproof spray seasonally
  • Check seams for debris that could compromise seal

Odour Management

  1. Ventilate: Remove after wear; air in open space
  2. Deodorize: Use UGG Shoe Renew spray
  3. Dry thoroughly: If damp, stuff with newspaper to absorb moisture
  4. Alternate pairs: Don't wear same pair daily

UGGRenew & Professional Care

Where available (check UGG official regional offerings), UGG's refurbishment service can deep-clean and restore Classics. Note: Standard warranty does not include repairs; it covers manufacturing defects only.

OD's Care Kit Recommendation: Stock official UGG Care Kit (Protector, Cleaner & Conditioner, Brush, Eraser) at purchase. It's a small investment that extends product life by years.

7 | Responsibility & Sustainability — People • Planet • Product

People

Inclusive community focus; training and empowerment initiatives, with programmes addressing gender equity, anti-harassment training, and leadership development in supply chains.

Planet

  • Material innovation: UGGplush™ (upcycled wool), SugarSole™ (renewable sugarcane EVA)
  • Product longevity: Pre-treatments, durable construction, UGGRenew refurbishment
  • Packaging improvements: Reduced materials, increased recycled content
  • Energy transition: Movement toward renewable energy in owned operations
  • Impact reporting: Ongoing transparency and goal-setting

Product

Long-lasting designs that prioritize durability, refurbishment initiatives (UGGRenew where available), and responsible material sourcing principles.

OD's philosophy: We prefer brands that back style with substance. Our role is to help customers buy well, care well, and wear longer — the most practical sustainability of all.

8 | Authenticity, Counterfeits & Warranty — Buy Safe, Stay Covered

How to Ensure Authenticity

  • Buy from authorized retailers: UGG direct, UGG stores, or authorized partners like OD's
  • Check domain names: Be wary of sites using "UGG" in the URL (e.g., uggbootsale.com)
  • Price reality check: 70%+ discounts on "new" UGGs = almost certainly counterfeit
  • Inspect quality: Real UGG has consistent stitching, quality linings, proper branding, and official packaging

Red flags for counterfeits:

  • Extremely low prices
  • Poor stitching quality
  • Thin, synthetic-feeling liners
  • Misspelled labels
  • No official UGG packaging/security tags

The Counterfeit Problem

If you purchased from an unauthorized source:

  • UGG will not process exchanges, refunds, or warranty claims
  • Credit card disputes may help, but outcomes vary by provider
  • You have no recourse for quality issues

OD's Authenticity Promise: Every UGG item we sell comes via the brand's official UK distribution network and is fully eligible for manufacturer support and OD's aftercare. 100% guaranteed genuine.

2-Year Warranty (Summary)

Coverage: Manufacturing and craftsmanship defects for up to two years from purchase date with proof of purchase.

Where to claim: Contact your original place of purchase — for OD's customers, that's us. We triage and handle the entire process.

What's covered:

  • Stitching failures not caused by wear
  • Sole separation from uppers (if not due to excessive use)
  • Material defects (discoloration, premature deterioration)

What's NOT covered:

  • Machine-washed or dry-cleaned items
  • Alterations or modifications
  • Excessive wear and tear
  • Water damage on non-waterproof models

  • Improper care or storage

Process:

  1. Contact OD's with photos and proof of purchase
  2. We assess and advise on warranty eligibility
  3. If approved: Inspection, then exchange or refund
  4. Note: Repairs are typically not offered; replacement is standard

Keep your receipt. For OD's purchases, we're your first point of contact — no run-around, fast resolution.

9 | FAQs & The OD's Difference

UGG-Specific FAQs

Q: Do UGGs run big or small?

A: Neither — generally true to size. Expect early snugness; liners compress and mould for a custom fit over 2-3 wears.

Q: Do Classics stretch?

A: Linings compress and conform; the outer suede doesn't "stretch" significantly. Start true-to-size for best long-term hold and comfort.

Q: Slippers: bare feet or socks?

A: Both work beautifully. If you'll regularly wear thick socks, consider half-size up where available.

Q: I have wide feet (E or EE width). What should I do?

A: Start true to size — the liner beds in and accommodates width. If you're EEE-wide or have bunions, consider going up half a size.

Q: Can I use orthotics or insoles?

A: Most slippers and Classics aren't designed for bulky orthotics. Choose roomier silhouettes like Neumel or waterproof boots if you need substantial insole space.

Q: How much growth room should I leave for kids' UGGs?

A: Leave 0.5–0.7cm (about ¼ inch) maximum. More than this causes heel lift, rubbing, and reduced thermal efficiency. Kids' feet grow fast, so plan to check fit every 2-3 months rather than over-sizing significantly.

Q: My child is between infant and junior sizing. Which should I choose?

A: Always measure their foot and use the length guide. The age ranges are approximate — some 4-year-olds wear UK 10, others wear UK 12.

Q: When should my child move to adult sizing?

A: Once they reach UK 6 (Junior), transition to adult women's sizing (UK 3+) for better style selection and more accurate fit. Junior UK 6 ≈ Women's UK 3.

Q: Do waterproof styles fit differently?

A: No — true to size. Just account for thermal/winter socks if you'll be wearing them regularly.

Q: What if I'm exactly between two whole sizes (e.g., between UK 6 and 7)?

A: For snug, barefoot wear: Choose the smaller size (UK 6). For thick-sock wear: Choose the larger (UK 7). The liner will compress to fit either way.
