First let me say the customer service has been fantastic. I had a small defect (sandals) and they sent me a new product without hesitation. I have had many slippers over the years. Some are good and some are bad. These Slippahs are Gr8! The contoured/curved support of the insole is better than most professional orthopedic insoles. So if you want to keep your feet happy and healthy, you can't go wrong with these slippers!
