  • 1. Place a piece of paper against a wall.
  • 2. Stand on it with your heel against the wall.
  • 3. Mark where your longest toe ends (both feet).
  • 4. Measure from the edge of the paper to both marks in centimeters.
  • 5. Use the longest foot measurement and match it up to our size chart.

Care

Gently brush with a soft, damp sponge to remove loose dirt. Treat stains right away with a gentle cleaner. Air dry away from heat.

The faster you go, the farther you go, the more you’ll see. That means more alpine meadows, more sunset views, and an extra-full camera roll. Cruise down muddy trails, hop across boulder fields, and slide through scree. Our lightest men's hiker to date with the KEEN famous fit and all-terrain tread, NXIS Speed is ready for whatever your A to B looks like.

• All-Terrain Tread: Our proprietary horseshoe tread has deep lugs for extra grip on any trail surface.

• Iconic Toe Protection: Move fast with confidence, not stubbed toes. The split toe cap strikes a balance between protection and feel.

• Famous Comfort Fit: 18 years in the making, our original fit holds your heel firmly in place while giving your toes room to spread out.
