I bought these in lace late last year... and I would highly recommend from my purchasing experience to do so a full size bigger, maybe up to a size and a half as they do not have the advantage of a zipper for easier access.  I hoped for them to reach me closer to mid-thigh (I'm 5ft 7); they hit me just at the top of my knee... re: the shoe material this isn't as pliable as I would prefer, however when I finally got them on after a bit of a struggle - they really did look lovely. As it is, I'm pretty limited in what I can wear them with ie stockings, leggings or bare.

Also for added comfort, insert an insole as there is barely any cushioning and as a result, feel a bit achy after awhile despite the low heel.

I would return them for these reasons, but as I live overseas its not really worth the added financial charges/trouble for purchases under 50 bucks ... so I accept the risks when such an item turns out to be a disappointment or less than I had hoped *sigh

Hope this helps =)
