Ultra Swift
Ultra Swift is a trail-running shoe for moving quickly over technical terrain. Its dual-density midsole pairs XtraFoam at the heel with FastFoam at the forefoot. A breathable mesh upper, internal arch sleeve and gusseted tongue support fit and debris protection, while an EXTS rubber outsole with zoned traction and 3 mm lugs targets braking and push-off on wet and dry ground.
