3 years ago i have the first version of Trail glove then other brands of shoes road/trail running. Until i was diagnose PF Plantar Facitise u know the muscle of your forefoot need to be stretch always.The Doctor recommend to wear the Orthotics insert freakin expensive and also unfortunately it does not work for me and not for everyone. But this Amazing Merrell Vapor Glove it does works brilliantly i used it every day work run gym casual.Its amazing !!!!!! No more plantar facilitis PL and back pain. But Please before you try go first the 4mm drop then transition to zero drop and go easy and listen to your body. I like the vapor glove toe box with toe guard design its fantastics. Suggestion: the Trail glove 3 needs to design like Vapor glove outsole for more flexibility and contact. Note:Before you buy just go to the store near you that carry Merrell brands because this sizing is totally different from your usual shoes. I wear 9.5 regular running shoe any brand, but the Vapor glove i use 8.5 with socks (thin running) or without.
