Take on the Roughest Trails
From rocky, high-altitude trails to days-long backpacking trips, the MTN45 provides plenty of rebound and support to help you cruise through the most challenging hikes. The key is Danner's EnduroFoam® Plus midsole, a robust cushioning system designed for greater energy return. The MTN45 delivers plenty of stability too, thanks to a super-grippy Vibram® outsole, combined with a premium leather upper inspired by Danner's legendary Mountain Light hiker.
Key Features of the Danner MTN45 3" Jet Black
-
Nubuck Leather Upper: Top-grain leather sanded on the outside for a slight nap and velvet-like feel — extremely durable, with a shorter, more comfortable break-in period.
-
Removable OrthoLite® Footbed: Multiple layers of varying density for maximum cushioning and support, made from open-cell polyurethane for better heat dissipation and air circulation.
-
Danner® EnduroFoam+ Midsole: Nitrogen-infused supercritical foam prized for rebound, shock absorption, and weight-to-performance ratio — thicker and wider for a more cushioned feel while still delivering excellent energy return.
-
Vibram® Megagrip N45+ Outsole: Specially formulated for superior wet/dry grip, with a wider Traction Lug platform to boost stability on uneven ground.
-
Rock Plate: A lightweight, supportive TPU rock plate for stability and underfoot protection on rough, uneven terrain.
-
TPU Mudguard: A LIBA® Smart TPU mudguard for increased durability without adding weight.
-
DT-6 Last: Inspired by trail running, with an 8mm heel-to-toe offset and slightly more width in the forefoot for stability and an everyday-wearable fit.
-
Recraftable: Eligible for a boot stretch, basic, and resole recrafting packages, extending the life of the boot. Note the liner can't be replaced on this style due to its sleek, minimal outsole construction.
