Breaking in a new pair of shoes right now and one problem I often have is that the top part of the heel section (where there is sometimes a loop attached for pulling on the shoe) curves back in, pressing on my Achilles tendon when the shoe is worn - you can see the curve in this product
For me, this always rubs really badly and results in a serious blister, until the shoes soften and stretch.
Now, some people will no doubt say that I should stretch and soften this part to shape it before wearing the shoes, but why not just make it so it doesn’t curve in there?
Is it that I have odd shaped feet, and most people need shoes to curve inward there like that? Is it because if they made it to fit, it would stretch to be loose?
