I love these boots! I only wore them around the house the night before i tested them on the slopes. I went boarding for 2 days in a row and they were 100 times better then the rental boots i had to use for the past month. The flex is great and I think they are super comfy. I got the 8.5(blue steel/disco) when I wore an 8 in rentals. 8.5 was a great choice they would have been way too small.
