Enjoy excellent comfort and advanced support with the GEL-KAYANO® 27 running shoe. The redesigned mesh upper helps keep feet cool, while the sole is more flexible to help promote a more natural roll through the gait cycle. This process starts in the heel with added flex grooves that isolate the initial impact to force a softer and smoother feeling at footstrike. At midstance, the foot should stop pronating and re-supinate for an efficient toe-off. This shoe also incorporates DYNAMIC DUOMAX® technology to help support the foot and increase stability for runners whose feet roll inward too much (overpronate).
