I'm guessing around 30 degrees - the foot pocket is built up internally so your foot really angles upward relative to the blade. I'm getting a very snug fit with 5 mils. I think it would be interesting to try socks that are smoothskin on the outside - these would probably slip in more easily and be possible to use in colder conditions. As it is I found if I tried to slide the sock in with my feet in them I could do it, but my toes got scrunched - this way its pretty comfortable.
