Shoe Sizing Tips & International Shoe Size Chart:

The Beast '16 and Ariel '16

The Beast '16 and Ariel '16 are fitting slightly smaller than the previous model. We recommend sizing up a half size from what you wear in the Beast '14 or Ariel '14 for a more comparable fit.

Running Shoe Sizing

We recommend ordering Brooks running shoes 1/2 size to one size larger than what you wear in casual or dress shoes

Select width

For women's footwear, B is the standard width. 2A is narrow, D is wide, and 2E is extra wide. For men's footwear, D is standard, B is narrow, 2E is wide, and 4E is extra wide.

Unisex sizing

Ladies, when orderding "unisex" shoes, order 1.5 sizes smaller than your usual women's size.

Get fit

Whenever possible, visit your local running and walking footwear store for a proper fitting.
