Ultra 100 Trail Running Shoe - Women's

What Our Gearhead® Experts Are Saying:

"I put the Ultra 100 Trail Running Shoe through a fifty-mile effort with significant vert, and the maximum cushion EVA blend kept my feet feeling protected well into the back half of the race. The Vibram Megagrip outsole handled everything from wet granite to dry hardpack without a single sketchy moment, and the larger volume fit accommodated the swelling that always comes with long days on trail."

Ultra distances demand a shoe that can absorb punishment across dozens of miles without losing its ability to protect your feet when fatigue is at its highest. The Dynafit Ultra 100 Trail Running Shoe was built for exactly that kind of effort, delivering maximum cushion in a package that still feels lively and responsive rather than soft and slow.

The EVA blend midsole stacks generous foam underfoot to absorb impact and return energy through every toe-off, while the rockered platform and Heel Preloader technology work together to minimize heel slip and drive quick, powerful transitions from one footstrike to the next. Vibram Megagrip rubber with 4mm lugs handles both wet and dry surfaces with confidence, and the low-profile lug pattern transitions smoothly from technical trail to road sections without clunking. A larger volume fit accommodates the natural foot swelling that comes with long efforts, and a seamless tongue design keeps pressure points and lace ends out of the equation entirely. At under ten ounces, the Ultra 100 carries its cushion without carrying its weight.
