I took these shoes with me to the Eco-Challenge which was a 671 Kilometer stage race on the islands of Fiji. I also trained in them extensively prior to the race. The shoes excelled for my training fast packs and provided remarkable stability when I had a medium sized racing pack and I was moving over tough terrain. The grip is good in wet environments and great in loose desert sand and dust. They were "fast" and stable on dry rocky terrain and I never felt they were lacking in grip. The lacing and tongue system is a little different than traditional shoes and I think it is an improvement and the tongue was never bunched up or loose. They hold up better than most shoes and I haven't experienced pre-mature holes in the fold part of the front toe box, pronation issues, or degradation of the heel cup. The shoe will fit average feet size but I have a wide toe box and super high arch. The shoe still worked for me. People with skinny feet should try them out before purchasing.
Great shoe for trail running, fast-packing, adventure racing, and technical terrain. Traction is excellent in snow, mud, and mixed. Upper drains very well and dries quickly after stream crossings. Price is not the lowest, but sometimes you really do get what you pay for.
I needed a shoe that would be great for everything. The Responsiv Dynamic makes a great everyday shoe for all-day comfort at work and out on the trail. Even comfortable and performance on steep, rocky hikes in Arizona. Highly recommended!
