I haven't used these shoes at all since my last post. It seems that the aforementioned heel issue actually rubbed my achilles enough to cause substantial inflamation, such that in the interest of a faster and definitive recovery I've been limiting my hiking mileage all summer. I did a 28 mile dayhike on Monday with almost no flare up, so things appear to be headed in the right direction.
Hopefully the 101s have a heel cup that is kinder to my feet.
