Because it?s a wedge I knew there would be added pressure on the balls of my feet, but I was willing to deal with mild discomfort since I wanted something a little cuter to wear with my dresses. Ive been wearing Birkenstocks almost exclusively for several years now. I like it a bunch, its not too too hard for her. Super cute and comfortable too. I will be happy enough using this rack for a while, but only knowing that it is temporary. Short review: get these headphones. Let me begging by saying, this product is truly remarkable. This rack is decorative as well as useful. It should never indicate Y-Axis down or up separately (same for X and Z Axis) otherwise it wont function optimally. These are now poorly fitting uncomfortable ugly slippers.
