ASICS GEL-Kayano 26 Women's Running Shoes Birch/Champagne : The ASICS GEL-Kayano 26 running shoes provide many benefits for runners who want a supportive and comfortable training shoe: FLYTEFOAM(TM) Propel technology in the forefoot and under the heel creates a springy feel after every step. More aggressive sculpting of the rearfoot foam and GEL(TM) technology for better shock absorption and smoother transitions.
