Keen sizing

KEEN sizing is known for roomy toe boxes on many outdoor models — width/volume often matters more than a simple “runs big/small” length label. Our guides call out when a model is roomy versus when length itself needs a half-size change.

Use the converter for length bridges, then read the model page for volume notes. Outdoor peers: Merrell, Salomon, Hoka.

Fit tips

• If your toes hit the end in a pointed sneaker last, KEEN’s wider forefoot may feel TTS even when the length chart matches.
• Trail socks add volume — size after you pick the sock, not before.
• Confidence badges explained: methodology.
