Love them!! Springy is the first thing I thought popping them on my feet. Light and springy, perfect little foot cradles. Dual lacing feels like a complete game changer. I have a wide forefoot and love a wide toe box that lets my toes splay BUT it means my feet slip and slide within the shoe unless I make the lacing super tight. However super tight lacing irritates the top of my feet when I’m running down hill or on technical trail and became a big issue during UTAMiler. Mount to Coast have eliminated the issue with their dual lacing system. They fit like a glove and I love them. The H1’s small lugs were perfect for my neighbourhood trot that involved a bit of trail, footpath, grassy verges and mud. The cushion feels like a dream without interfering with stability when the trail got technical. Steep downhills are great, my foot didn’t slide to the end of the shoe so my toes were happy. 20kms of fire-trail and I wasn’t itching to take my shoes off post run. That’s saying something! I’m really excited about these shoes! Size guide, I can usually fit into a 9 in Hoka Mach/Speedgoat/Mafate and Altra escalante/superior/olympus but prefer a 9.5.These 9.5’s fit more like a 9.
