Sock Geek Says:

Discontinued by Asics so sizes and colors are limited.

Do you love the Asics Kayano sock fit but want just a little more performance.  Your wish has been granted with the Kayano Wool running sock.  Merino Wool adds breathability, temperature regulation, and natural odor resistance.  Anatomically correct Left/Right foot construction with high density, not bulky, cushioning.  Articulated arch band for a superior mid-foot fit.  Forward thinking flexible horizontal lace pad cushioning keeps the shoe lacing from putting too much pressure on the top of the foot.  "Y" stitched heel gore for optimum fit and reduced slippage in the heel.
