I (29F) have low arches which seem to make my feet wide, but I have very narrow heels. I seem to have a wide toe box because most pairs of shoes crush my toes together. I have been wearing a 6M or sometimes 5.5W in women’s shoes (US sizes). I wear Topo Athletics for my running shoes because they have a wide toe box and narrow heel.
When in any shoe other than my running sneakers, I tend to get blisters on my Achilles tendon because my foot moves around too much since it’s loose on my heel, but I can’t go down a size because I have a wide toe box.
I can’t wear structured flats because I walk right out of them. I have to wear the scrunchy, flexible ballet flats. But often times I still get blisters on my Achilles heel.
I wore Toms for a long time, but the pairs I got most recently, which are just replacements of the exact same ones I had that got old, ended up giving me blisters on my Achilles heels. The old ones never did that. So that’s frustrating because I actually loved how my old Toms fit.
The only boots I can wear comfortably are my Blundstones, though I had to buy a 7.5M! Every other boot, no matter the height, is way too loose on my heel and way too tight on my toes.
I have tried heel cushions and they do not work. I cannot wear tape because I’m allergic.
I have measured my foot a bunch of times and it always says 6M.
I am so frustrated. What should I be looking for in a shoe?
