I started a running program after a few years off. I have flat and narrow feet and needed heavy arch support to help with my overpronation. These shoes fit the bill perfectly. They are light, offer great support and have virtually eliminated all the knee pain I was experiencing with my 2 year old Asics GT-2150's. I like these so much I bought another pair. Amazon Prime is great too as it allows me to get my orders within 2 business days.
