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). The midsole integrates SPACE TRUSSTIC™ technology, which provides stability and reduces the overall weight to help promote a smoother transition from footstrike to toe-off. This added stability is complemented by deeper forefoot flex grooves that create a smoother roll through toe-off, allowing the shoe to move more naturally 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 is an excellent choice for both competitive and non-competitive runners looking for an everyday trainer that combines comfort with support.
