The inside heel came out of my Solovairs (Docs) and I am unsure the best way to secure it inside my boot again.
For the most part it is not a big deal, but it does get annoying when it slides out under my foot.
I thought maybe shoe goo, but I think that may be too permanent (and messy).
Oh, yeah, those don’t look comfortable. I’ve a low instep, so I bought some cork insoles. Little more expensive but very nice.
They are amazingly comfortable, if they fit in the shoe. Dr Scholl’s has machines in some stores, you stand on it and it determines the best insoles for you.
