ADDITIONAL FITTING INFORMATION

Accommodating Fit: Many of our standard widths feature a comfortable, accommodating fit due to our hands-free toebox design.
Choosing Your Width: If you typically require a wide fitting, our Wide (2E) options are a great place to start. For the most generous fitting with maximum volume and width in the forefoot, select our Extra Wide (4E) models.
Fit Recommendations:
- If you are between widths, for example standard to wide, and still experience fit issues, consider trying a wide (2E) option in your regular size.
- For very high arches or very high insteps, an Extra Wide (4E) model can provide more room.
- Thin socks can provide a slightly less snug fit.
Still Unsure? Our customer support team is happy to assist with detailed fitting advice to help you find your perfect pair of Kizik shoes.

Comfortable shoes that run big
Love these comfortable stylish shoes. I was able to walk 5 miles right out of the gate and no blisters! The shoes run big, I’m typically an 8.5/9 (depending on brand) and turns out a size 8 fits me just right! Thankfully returns and exchanges do not cost anything to ship back.
