My husband hikes our dogs for a mile or two each day, and almost every day. After approx 2 years of owning and wearing these boots, they have started to lose their waterproofing and developed a split on the side of the leather at the sole. I did a repair, but as we're going to be away hiking this summer, I decided to get him a new pair to avoid us being away and there being a problem with the boots. After bringing several more expensive pair of boots home, hubby asked if I could get him the same pair, as he loves them - comfortable and durable. I just placed an order for a new pair... same brand, same style... Hi-tec Altitude IV. My hubby says thank you!
