The upper is constructed with a redesigned mesh knit while the sole is more flexible to help promote a more natural roll through the gait cycle. Featuring a breathable knit mesh upper for a lifestyle aesthetic while helping runners keep cool, this shoe also incorporates a flexible midsole that helps promote a more natural roll through the gait cycle. This effect starts in the heel with added flex grooves that assist in isolating initial impact to force a softer and 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 DYNAMIC DUOMAX® technology to help support the foot and increase stability for runners whose feet roll inward too much (overpronate). The midsole also 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 for a smoother roll through toe-off, helping the shoe move better with the natural motion of the foot. Lastly, a large section of reflective material in the rearfoot helps keep runners visible when running in low-light conditions. The GEL-KAYANO® 27 MK model is an excellent choice for both competitive and non-competitive runners looking for an everyday trainer that combines comfort with support.
