Just tested the new Flow NX2-SE in a shop with my Nitro boots... well... we tried a lot of settings on the "toe "what ever" strap and it didn't work without manually pushing it up to the right position after stepping in... I finally switched to the NX2-AT with the "classic" flow strap, this one is really great! I Think Flow has to redesign the new "toe strap system" because I really don't think it will work really well
