My wife and I loved these so much that I bought three more pairs in black, white, and beige.  These transform her from 5'2 to 5'8 in a flash! Lol  While she hasn't worn them out of the house yet, with her thigh highs we're having tons of fun!   She normally wears a 5 1/2 to 6 in heels, but the 5's fit perfectly.  They are very good quality and have held up well.
