Designed for maximum cushioning, energy return, comfort and protection without hindering performance and movement. Breathable air mesh upper. Flexible TPU overlays provide lightweight, targeted support. No-sew construction reduces irritation and the likelihood of blisters. Heel pull loop for an easier on and off. Lightly padded tongue and collar for added comfort. Soft textile lining offers a great step-in feel. Foam insole for extra underfoot plush. Midsole: ; Hoka One One midsole foam is 30% softer than in most traditional running shoes and has 2.5 times more volume. This dissipates up to 80% more shock associated with heel striking and allows up to 20 mm of compression in the heel. An oversized design helps reduce the rate of pronation and supination by promoting stability upon impact. Ultralightweight materials make it 15% lighter than traditional running shoes. This makes running uphill just as enjoyable as running downhill, with less fatigue. Rocker midsole geometry and low heel-to-toe differential encourages proper form by allowing for an easier mid-foot strike. Midsole Differential: 5 mm. High-abrasion sticky rubber outsole delivers reliable traction and durability. Imported. Measurements: ; Weight: 9 oz ; Product measurements were taken using size 8.5, width B - Medium.
