The Dynafit Ultra 100 Running Shoes Women in Nimbus/Black Out are maximum cushioned trail shoes built for ultra distances beyond the marathon. A Vibram® Megagrip outsole with 4 mm lugs handles technical ground, while a roomy last and thick midsole keep the feet working at hour eight and beyond.

• Maximum cushioning: the thick midsole is built for the back half of an ultra, when a firmer racing shoe stops protecting the legs.
• Vibram® Megagrip outsole: the compound holds on wet rock and root as well as dry trail, which is where most trail shoes are decided.
• 4 mm traction lugs: the lug depth grips soft ground without becoming clumsy on hard packed sections and road links.
• Rocker geometry: the rockered profile helps roll the foot through the stride when running form starts to fade late in a race.
• Maximum Volume fit: the roomy last leaves space for the foot swelling that always happens over ultra distances.
• Covered lacing: the flat laces sit under a cover so they cannot snag on undergrowth or come undone at distance.
• Reinforced heel and toe: the added protection at both ends takes the impacts that rocky descents deliver.
• Breathable upper with padded tongue: the thinly padded tongue and breathable upper keep weight and heat down on long days.
• 259 g with a 6 mm drop: the shoe stays reasonably light for its stack height, at a moderate 6 mm heel to toe drop.
