Just wore these for the first time, they were pretty awesome. I have small ankles and these fit great. By the end of the first day my toes were numb, but I think that was just breaking them in some. The second and third day they were fine. I wear a size 7 shoe; I got a 7 1/2 in these, maybe should have gotten an 8.
I didn't get the battery pack, maybe later.
I would recommend these boots! Plus they look great :)
