The Xtreme is a great speaker with a couple cool extras. Problem is, I can’t seem to find a cargo rack or basket that fits them. Wanted to have these for my wedding. Now the bass is much more solid and controllable while still sounding big. I was annoyed I was led astray by those people commenting about sizing. However the width by my forestep was a little small and I was starting to get callus/bunions and it was painful because the shoes doesnt have much stretch or give when walking. One thing I don’t like is it doesn’t work if the clips on the frame are mounted too deep in, as long as the clips to whatever frame you buy is on the frame itself, and not the paper part inside, then you’re good! I have 9 1/2 EEE feet, and the size 10s fit like a glove -- meaning just right. By the way it’s not noticeable under clothes, nonetheless, if you are wearing skin tight clothes it may show through. I needed this script for an audition late last year in Chicago.
