KEEN Sizing and Fit Guide
Since April 2023, KEEN Europe primarily displays available sizes as EU sizes. KEEN states that the size chart on the specific product should be used because Fit Predictor recommendations and fit can vary by model.
Adults – Sizing Logic
| Area | Official KEEN guidance |
|---|---|
| Adult footwear | EU sizes are used on European product pages. |
| CM / JP | According to KEEN this is the total insole length, not actual foot length. |
| US / UK conversion | Check directly in the size chart for the desired product. |
| Fit Predictor | May provide a different recommendation depending on model. |
Children
| Category | EU sizes |
|---|---|
| Toddlers | 19–23 |
| Little Kids | 24–31 |
| Big Kids | 32 / 33–39 |
Fits and Widths
| Version | Manufacturer description |
|---|---|
| Original Fit | Generous forefoot space so toes can spread naturally. |
| Contoured Fit | More streamlined and follows the contours of the foot for a secure, closer fit. |
| Men Regular | D / standard width |
| Men Wide | H / widest KEEN fit |
| Women Regular | B / C / standard width |
Important: Do not treat CM insole length as actual foot length. KEEN explicitly states that the insole should be longer than the wearer's foot.
