I love Asics running shoes. I have a high arch and I under pronate. I always buy my running shoes 1/2 size bigger and these fit perfectly. My feet are long and narrow and usually shoes are too wide but I got these in the B width and they fit perfectly. I have had other pairs of asics and they are very durable and supportive. I am a moderate runner. I run mostly sprints a few times a week and also power walk so these are perfect for me. They feel amazing. I used to have pain in my legs and heels until I started wearing Asics. It has also helped correct my stride. I highly recommend these shoes and all the Asics brand.
