I've always checked out this site before buying hoops shoes:
Kicksology. It appears they are shutting down pretty soon though.
I've always found highs to be a little restrictive. Also, I sprained both of my ankles very severely while wearing hightops. If ankle support is what you're after, I'd go with a mid and go with a
McDavid laceable ankle brace , especially if one of your ankles is being held together by screws. There is no support better than these things. But remember you'll pay the price is restriction; you just have to determine what's more important -- staying out of the hospital or having less mobility.
Right now, with my ankles in relatively good condition, I wear a mid, with no ankle support. Then again, I don't play like I used to.
