Sneaker recommendations?

Hey peeps, I’m looking for sneaker recommendations that won’t kill my feet and cause blisters or calluses on my pinky.

I need wide shoes that are light and comfortable, though I have the problem where normal is tight and wide is too big. I am using the New Balance walking/running 680 shoes atm and they’re comfy, but I’m not sure if they’re all day in a festival under blistering heat proof.

Anyone got any good recs that helped you survive with no problem?

Ps: Last year I averaged 21,000 + steps a day and well.. I still have the calluses (if anyone has a remedy for that I’m all ears)
