The soles on these shoes make them very comfortable, and contrary to what you would think from such high heels, they are very stable as well.  The only issue is the ribbons- they are a little short to be able to tie them above your calf so that they'll actually stay up.  But, they're also too long to tie them at the ankle.  Until I can find a way to make them stay, I think I might just go buy some ribbon and make longer ones.
