Dayhhiking probably almost weekly for 15+ years, have worn Altitude IVs maybe half the time since I bought them just over 2 years ago.

Hi-Tec Altitude IV are without a doubt the best hiking footwear I have ever owned. Zero break-in. Excellent comfort/arch/ankle support. Traction and durability in near-vertical terrain, even on steep Utah slickrock. Waterproof. Have actually gotten compliments both on the look, and also on the performance from other hikers who didn't have the same traction. To date, a tiny bit of scuffing and and creasing in the leather, FAR less than I would expect considering what they've been through. Soles appear new!
