This not-buying-shoes policy, Drince. I don't like it.
I bought two pair myself, both for serious walking. My fit issue is a B-width foot with a very narrow heel so everything with a back slips. Solution? The very good salesguy at the Mall of America's The Walking Company found two.
Exhibit 1: the velcro strap at the back
Now, normally I would not wear a Mary Jane but I am desperate enough to compromise. You know, the shoe really looks okay on. Who knew.
Exhibit 2: the heel strap
The salesguy kept calling these
gladiator sandals. I don't see it but I did take a really long walk in them yesterday. No blisters, very comfortable, and pretty nice looking, too.
