Toe Box Explained

In brief: The toe box is the front section of a running shoe that surrounds the toes. Its width, height and shape decide how much room your toes have to splay.

What is the toe box?

The toe box is the part of the upper that wraps the front of the foot, from the ball of the foot to the tip of the shoe. It sets how much space your toes have to spread out, both in width and in height. Toe box shape is one of the biggest factors in whether a running shoe feels comfortable over long distances.

What it does

Your toes splay naturally as you land and push off, so the toe box needs room for that to happen. A roomy toe box lets the foot work properly and reduces rubbing, blisters and bruised toenails. A tight or shallow toe box can cause pressure, numbness and toe problems, especially on downhills and longer runs.

Types and variations

Toe boxes range from snug and pointed on some performance shoes to wide and rounded on natural-fit and wide-fit models. Some brands are known for generous toe boxes; others run narrow. Many models also come in wide and extra-wide fittings for runners who need more room.

What to look for

You want roughly a thumb's width between your longest toe and the end of the shoe, and enough width that your toes are not squeezed. Numb toes, black toenails or rubbing at the sides are signs the toe box is too small. Try shoes later in the day when feet are at their largest.
