I bought my wife these shoes to replace her old sketcher walking shoes thinking the memory foam would be great. After about 1 hour of walking in them, she showed me how the memory foam in the middle of shoes had gotten a crease; she said it felt like she was walking around with a big wrinkle in her socks - She kept wearing them in hopes the crease would go away; however, she then developed extreme heel pain. Once she stopped wearing the shoes, the pain thankfully went away after time and rest. She now sits with a pair $75.00 shoes, which were only used for a total of 2 full days, and she's unable to wear them. WORSE SHOES EVER!!!
