After using these for 3 seasons, I think these are an improvement over my old leather boots for backcountry touring, but if I plan to do much telemark turning/downhill, I wear much stiffer plastic 2-buckle Garmont Veloce tele boots on same b/c skis. I bought these to replace old leather tele boots that I could never lace tightly enough and were too stiff through the toe/forefoot (smashed toe joints, blistered toes & heels). PROs: 2 buckle straps do an excellent job of holding my heel tightly in the boot for diagonal stride, moreso than the old leather boots (no heel blisters); ankle support is excellent; lighter weight and more flexible than leather regardless of temperature; warm enough for me. CONs: too flexible in the forefoot for good control on tele turns, as noted by others; fit too snugly throughout incl. toe box, as noted by others, and must wear thinner socks; feet get wet on warmer wet snow days (unlike my waxed leather boots).
