ive always had weak ankles, and early last year i twisted one so bad that i had to be in crutches for 2 weeks. every since then ive worn ankle braces literally every time i ride. i have some protec braces that i got from tactics skateshop. i'm on my second pair, since my last ones wore out.
i wouldnt be able to really ride without braces. they dont get in the way at all, at least for me. the most annoying them about them is having to put them on, since it takes a while, but its well worth it.
