These are probably the most comfortable shoes I’ve ever worn. They’re like walking on air BUT they have a major problem. When walking on smooth surfaces the bottoms stick to the ground causing one to fall forward. It happened to me. Luckily I was able to break the fall but my friends wife fractured her kneecap. After further research online I discovered that it’s happening to a lot of people. It won’t be long before Skechers realize they have a major problem and pull these shoes off the market.
