I definitely agree with what everyone else is telling you.

However, I did notice one thing: you said you were using Superfeet insoles with these shoes. Have you used Superfeet before? Were you using them all day for four days on your AT hike?

The reason I ask is that I have heard that Superfeet take some “breaking in” and getting used to (although I’ve never tried them myself.) If you’ve never used them before, and put them on the first day of your 4-day hike, and left them in all day for 4 days, you might want to consider whether it’s the insert, and not the shoe, that’s causing the problem. (How do they feel without the Superfeet insert?)

I apologize if I inadvertently cast doubt on your skill or experience; it just wasn’t clear in the post, so I thought I’d ask. smile
