I tried to adjust them during work out. sheerness is crap All of my heels and pumps are Nine West and they are super comfortable. The white and silver are pretty much the same except the white has a white trim around the edges. Rockport has lowered its quality, but not its price. After wearing the slippers I had an allergic reaction on both my toes and I wanted to share this So that anybody who is prone to Allergies and other shoe problems Should not buy this product So overall a great purchase. I put these up against the jabra elite 65t and those blew these out of the water in terms of clarity of sound. I really have liked my older AD700 headphones for PC gaming these past several years. Cute and sexy.
