Whereas memory foam takes a while to rise back up from the shape its already taken. It?s the one I?ll probably run out of first. E dico per fortuna visto il costo. Much better quality for the same price. Ive played with them once, and my feet were very happy. I dont post very many reviews, but I realize that isnt fair of me. They look really cute and fit with pretty much any outfit, but the sole gets a little uncomfortable if you walk in them for a long time and the faux leather gets scratched easily. I?m not a handy women and I installed it all by myself in 2 and half hour without any extra tool. In terms of audio quality, I am kinda of spoiled as my sound card is modified with new capacitors and custom soldered burr brown opamps. The cord should not be coming apart like this after only three months of use.
