About a year and a half ago I bought a pair of Korkers Metal Head wading boots. Really liked them, the other day after getting out of the water I noticed the knob that the soles attach to was missing on one boot. I contacted Korkers and was told the boots were out of warrenty but send a picture. Ari from korkers contacted me back and said they appeared to be in good shape otherwise and to send them in and he would send me a new pair of the new White Horse Korkers at no charge. I've heard good things about this company and it seems that it's true. Great product and terrific customer service.
