I wear 10.5M and have very skinny feet. I can wear Brooks Adrenaline, but I have to lace them up very tightly to keep my heel in the shoe.
My foot isn't necessarily narrow (which is really a measurement of the width of your forefoot). But it is very thin, especially in the ankle. When I lace up, the sides of the eyelets almost touch. Narrow sizes don't work because they tend to be too tight in my forefoot.
Can anyone recommend shoes (high mileage trainers) that are tight in the heal and narrow, but not tight in the forefoot/toebox?
