Asked this same ? on FB but wanted to get as many ideas as possible so trying here too...let's talk blisters

I get horrid ones when I'm WALKING alot...have never ever had an issue getting them from running, weird. So, as you can guess, I usually come home from WDW with several...I get them on the bottoms of the same few toes each time I go. I fight through it because I'm dedicated to my vacation! But, what happens is that my race training ends up getting derailed because they end up too painful to run on...so I don't get any of my training runs in while on vaca. I walk the parks in good shoes (usually the same shoes I would run in, and I take a few pair to rotate each day), wear good running socks (have even tried the double-layer kind), I've tried body gliding my toes like mad, and pre-wrapping them in band aids...which never stay on for very long so don't do me any good. You would think after all these years, those particular toes would be so callused over from the blisters that end up layered on themselves that I wouldn't get them anymore, but nope, every time. Does anyone have this problem and do something magical that actually works to prevent them? I got a few suggestions on FB (a product called 2Toms Bilster Shield and then another suggested getting toe caps) that I may try, but I want as many suggestions as possible! I've never thought about it until now, but this problem really has me worried now for the 10k/half combos I'm doing at Tink and Princess...the plan posted calls for saturday walks followed by sunday long runs later on...hopefully I'll have something figured out by then!
