Runners often get caught up in the latest shoe that is marketed to make them run faster. Personally, I like a shoe that feels good. I want shoes that have a wide toe box and won’t rub my toes wrong.
Once, after a 1/2 marathon in Delaware, I took my shoes off to learn the more narrow toe box had chewed away a toe nail during the race. Others followed after a few days of unsuccessfully trying to hang on. Since then, I’ve worn wider shoes.
The Newtons I wear seem just about perfect for my feet. Like must of us, my feet aren’t exactly the same. There not mismatched to the degree where one foot needs another size. Both feet are either 9.5 or 10.0 depending on the shoe. A little wider shoe compensates for the minor difference in my two feet.
I’ll run in a pair of shoes until they fall apart. Over time my shoes do fall apart. Those old Newtons (the red pair) had about a year of running in them before they gave up the ghost.
