Great, durable, lightweight trail running shoe for wet/cold conditions in late late fall/winter. IWaterproof checks out, but still breathable (unlike Adidas Terrex where your feet sweat and shoes are way too heavy/bulky). This is my second pair of GTX, I wear Challenger 8 (non-waterproof) during the warmer/dryer spring/summer since this past year. They are less expensive than the Mafate X, and I don’t need the carbon plate or the heavier Vibram sole. Challenge 7 is about 2oz lighter if that matters to you. I run 3 to 5 miles, five times a week, on the smaller, off trail paths in Middlesex Fells Reservation that are steeper with a mix of gravel, dirt, lots of roots, and jagged rocks. I size up, 1/2 size for heavier socks to keep warm in the winter. I used to wear the much more expensive Nike GTX trail running shoe and HOKA is much better: more comfortable, ankle/heel cushioning +++, but still responsive, strong grip, and snug/solid fit. HOKA Challenger 7 GTX last longer too. The upper fabric— especially the front upper area & toe box is way more durable and better designed—resists tearing from branches, sharp rocks, etc. Dear Nike: you can add all the Gore-Tex you want, but if the fabric tears, even with one hole, your shoes are done. Anyway, I found the perfect trail running shoe with the Challenger 7 GTX. Fast delivery from Commonwealth. Really can’t ask for more.
