I am happy to report that after completing my 8 mile long run today, I am grateful that I purchased my shoes a half size larger. I am blister free and didn’t experience any pinching. I don’t think that would be the case if I had purchased shoes in my usual size, 8.5. I suppose I shouldn’t have questioned the pros at Road Runner Sports. What a relief, that could have gotten expensive. I am thinking of looking into some inserts for arch support. They were out of my size at the store.
