I bought these shoes and I've put about 50 miles in them so far and I like almost everything about them. My feet feel better at the end of long runs and they're one of my lightest shoes despite being so big. My problem is that on technical trails, my feet slip inside the shoes. The soles grip the ground just fine, but my foot has a tendency to slip inside the shoe, especially when the foot tilts to the outside on uneven ground. Are the insoles in these just more slippery than normal? Is there a good way to keep my feet in place better? This isn't a problem at all on groomed trails, but I'll be doing the Cheaha 50k soon and those are often far from groomed.
