The Brooks Trance 12 running shoe features a moisture-managing Element mesh upper with synthetic overlays that are strategically located to help provide a secure fit. A full-length caterpillar crash pad with independent yet integrated segments provides an exceptionally smooth lay-down, and a foam constructed saddle conforms to the foot for a custom fit. Full-length DNA is designed to tailor the level of cushioning to each individual's weight, pace, biomechanics, and running environment. BioMoGo midsole is designed to offer resilient cushioning and extends the full length of the midsole. Progressive Diagonal Rollbar (PDRB) begins at the medial heel and extends through to the medial forefoot to smoothly reduce excess pronation. DRB Accel is located at the bottom of the midsole in the midfoot to balance support and torsional rigidity with responsiveness for smooth and fast heel-to-toe movement. Stable Pod Configuration is a midsole/outsole design pattern intended to set the foot up for an efficient, balanced position from heel to toe. HPR Plus outsole with blown rubber in the forefoot to provide responsiveness and flexibility. Wt. 12.2 oz.
