I wish SoftSoap would sell this in a sturdy pump bottle and then sell refills in an environmentally friendly package. Its very low. So glad that I reordered. It could hold 18 pair of my size 7 shoes. Its just a cool movement. I chose same size as my tennis shoes. Maybe 1 year or heavy use? Will update you guys later lol- Kinda overpriced. I thought these shoes would be soft and would ease my foot pain. Aus Mangel an Alternativen habe ich trotz der teils schlechten Rezensionen den Adapter gekauft. La semelle est peut-être trop dure, jai limpression que ça raisonne jusque dans mes jambes.
