Enjoy Luxurious Comfort And Exceptional Support With The New Gel-Kayano 27 Running Shoe. A New Breathable Upper Mesh Helps Keep Runners Cool, While The Sole Is More Flexible To Promote A More Natural Roll Through The Gait Cycle. This Starts In The Heel With Added Flex Grooves That Isolate Initial Impact To Force A Softer, Smoother Feeling At Foot Strike. At Midstance, The Foot Should Stop Pronating And Re-Supinate For An Efficient Toe-Off. To Help This Natural Motion, We Incorporate Duomax Technology To Help Support The Foot And Increase Stability For Runners Whose Feet Roll Inward Too Much (Overpronate). The Midsole Also Integrates A Gender-Specific Space Trusstic Technology, Which Provides Stability And Reduces The Overall Weight To Help Promote A Smoother Transition From Foot Strike To Toe-Off. This Added Stability Is Complemented By Deeper Forefoot Flex Grooves For A Smoother Roll Through Toe Off, Allowing The Shoe To Move Exceptionally Well With The Foot. Lastly, A Large Section Of Reflective Materials In The Rearfoot Helps Keep Runners Visible When Running In Low-Light Conditions. The Gel-Kayano 27 Model An Excellent Choice For Both Competitive And Noncompetitive Runners Looking For An Everyday Trainer That Combines Comfort With Support.
