Yes. I can't wear Superfeet (heel is too large, gives me blisters on my heels) and bought some custom insoles at Trail Days years ago that I really need to replace. After hiking the AT you'd think I would know better, but I tried to use the insoles that came with my new boots last summer and had such terrible blisters I had to drop off a 10-day hike on day five. It was terrible (I have never had my feet swell to that extent, and I had never had to get off the trail before). I stuffed the old, supposed-to-be-worn-out customs into the boots and had no trouble after. It's depressing to look back on, and I do need to buy a new set of custom insoles for my boots. There are other off-the-shelf insoles out there, I'm just afraid to try them now.
