" I found no mention of the Spenco 2nd Skin"
I used ALWAYS bring Spenco Second Skin on all the hikes I led (operative word being "led). On my own hikes, or with my family members, our shoes fit better than that, they aren't heavy clod-hoppers, and no one ever rubs their hot spots raw. But with men (it's always men) along, they'll hike with a hot spot, past the blister stage and rub all the skin off. Then what you really need is a product like Second Skin.
Dena: I feel your pain (not your foot pain, but your shopping pain). Just in the last few months, I've realized Amazon sells more than books and have ordered all sorts of odd-ball items that I could find in Kenai/Soldotna or sometimes even Anchorage. The brand of sunscreen the kids don't complain about. Filter bags for the vacuum cleaner. Titanium tent stakes. Odd sized batteries. Etc. I just add items one at a time to my "shopping cart" until there's enough for free shipping or I need something more urgently. Anyway, they have Leukotape:
Or PM me and I'll send you a few feet by snail mail.
90% of you know this, but here's a UL tape tip: A full roll of any tape you bring (Leukotape, duct tape, Gorilla tape, etc) is too much. Wrap a few feet around your water bottle or a tube of sunscreen, film canister of FA supplies, etc. My knife sheath is a folded piece of heavy HDPE cut from a roll-up kid's sled. With multiple layers of Gorilla tape and blister tape wrapped around it for storage.
