Inserts
"I have two pair of Kenetrek boots. One pair of uninsulated, and one pair of insulated. What I have found with both pairs is that the support for the foot on the insole that comes with the boot hurts the bottom of my foot feels like I’m walking on a rock. It’s not the boots fault. Its just my feet. Both times I have contacted Kenetrex Customer Service and they have sent me the more cushion and flatter insoles. Once I have those put in the boots are a dream. I’m a Kenetrek customer for life. One because they built a damn good boot and the other is the outstanding Customer Service."
