I'm 5'10, 160lbs, 39 yrs old, training for a Marathon. Peak mileage will be 75-80. I have been training in Adidas Bostons for years.
I just bought a pair of Lightstrikes for races. They are not as light as I thought they would be, but I love them and want to train in them every day. Anybody train in these? How many miles are they good for?
