They do not specifically make any crossfit shoes in a wider size. All crossfit shoes come in medium width. However, on the bright side most crossfit shoes are made with material that will stretch to meet the needs of your specific foot, so there is a good chance you will not be in need of a wider shoe. But below I have listed some examples of crossfit shoes that can be used for wide feet:
Inov 8 Bare-XF 210– This shoe has an anatomic fit. In other words the foot will mold to your foot’s individual shape and contour. This anatomic fit will provide comfort for somebody with a wide foot.
Inov 8 F Lite 262 Mens– This shoe features a natural fit for a wide toe box in case the reason you suffer from a wide foot is a bunion deformity. If you tend to wear out shoes in the forefoot due to the width of your shoe this would be a shoe to consider.
Reebok One Trainer 1.0– Of the more traditional style crossfit shoes, the One Trainer is probably your best bet for a wide foot, with its large toe box and midfoot area.
