These are great boots! Very protective and comfortable. Zipper can be hard to zip at first, but gets easier as they break in. Inner liner loops on the new model are more fragile than the old model - my new set arrived with broken loops on inner liner string. Got a free replacement set with all good loops. May use my old liners cuz they have much stronger string loops and would be much quicker to lace up. Other than that, I love them!
