the first thing that always wears out on a pair of wading boots for me is the insole. so i've started upgrading them right away with the dr. scholls gel insoles. out here, you often need to hike muchos miles of stream/trail in a day of fishing and it can be pretty rough going with a lot of elevation gain/loss. and comfortable feet really help the enjoyment factor! so "gellin' like a felon" in your wading boots is a huge benefit. well worth $8 every now and then. just make sure your wading boots are big enough to take the larger insoles.
