I’ve worn flip flops daily since 2005 (yay startups that don’t care about dress code). High have no foot problems, arches are normal, my toes are strong and it helps with balance. The only time I wear socks and shoes is hiking and the gym (or fashionable shoes for going out). Retired in 2016 and started walking at least ten miles a day… in flip flops. Recently need a goal and got to a little over twenty. Ymmv
This is the biggest favor you can do for yourself. The developer experience is as easy as production without descending into container induced madness.
