The designer Miuccia Prada, on her side, did not blame the height of the shoes, but the silk little socks inside, which were slippery and moved inside of the shoes, preventing the models' feet from having a correct grip on the sole. Miuccia Prada also assured that the shoes sold in stores would have a lower heel, and that the little socks would be sewn into the shoes in order to prevent further slips. But many fashionistas rightly claimed that the socks, once sewn into the shoes, would be non-washable and would quickly stink and become grey. Consequently, the shoes have never been commercially sold.
