The only place they didn't fit me alright was around my ankles. I have small bony ankles. I also like shoes and jewelry to have a tight fit, perhaps there is supposed to be a little room in these, I have never owned a pair before. I wear ankle bracelets that measure 8.25inches if that helps.
When you list an auction there is a box for advanced options. If you want to list for 21 days (which is the max) you will be charged I think 750 credits on a monthly basis, and there may be some other things to read before you click another box to accept the terms of that option.
They will fit, but I think they would be loose around the ankles. That is what prevented me from keeping them, I have really bony ankles and wrists too though. If your ankles are around 10 inches I don't think it would be too much play in them.
