midsole

Traditional EVA midsoles returned less than 70 percent of the energy input, whereas the best new foams give back more than 85 percent.

The softer midsole is also more responsive, allowing me to better adapt to changes in terrain without slipping, without being so squishy that I feel every pebble.

It’s running shoe–like midsole kept my back from hurting even after being on my feet all day, and the slip-resistant sole kept the rubber side down on wet roots, a slippery deck, and in the mud.

Underfoot, a full-length carbon plate and heavily rockered midsole push you forward with each stride without feeling too exaggerated or stiff.
