Backpacker Mag Review
Dynafit Speed Mtn GTX
Our take We had our reservations about the slipper-like Speed Mtns, but after 54 days, 140 miles, and 30,000 feet of elevation gain without a slip in these svelte runners, we’re converts. “Most folks wouldn’t consider the route up Alaska’s Mt. Troy a trail at all: You have to run up a stream, ascend through a thick spruce forest, and then cross the rocky alpine zone—but the Speed Mtns easily handled the task,” says one tester of his backyard run in Tongass National Forest. The secret is in the durable outsole, which is made of a butyl rubber compound, like a car tire. Known for its weatherproofing, the butyl sole proved just as grippy on snowy forest roads as rocky singletrack. Diamond-shaped lugs vary in depth (up to a cleat-like 6mm) across the sole, while a tough canvas upper, climbing shoe-like rubber rand, and burly toe bumper protect the Speed Mtn from trail debris. And the cost for all those features? Ouch.
The details Our testers liked the speed lacing system, which keeps the shoes cinched evenly, but the
protective sleeve is tough to manage with cold fingers. Fit note: Dynafit ditched its standard lasts in favor of
a wider one for the Speed Mtn—meaning it fits larger-volume feet and allows for more toe splay.
Trail cred “The ballistic toe bumper kept my feet bruise-free,” says one Alaska-based tester with a history of broken toes.
