Asics are known for having a narrower heal and a large toe box. If you like the support of a running shoe but want room for your toes to spread out - try Asics. I recently switched to the GT-2000 after being in the Asics Cumulus and Asics Nimbus (both neutral shoes) for years while doing a lot of running. After a few unrelated injuries, I'm trying these shoes to help with a very mild pronation in one foot. As usual, the Asics are comfy right out of the box and don't need to be broken in. This could be because they are the right fit for my feet, or maybe they are just that awesome for everyone; I don't know. I'm giving them 5 stars after only wearing them for a few days, but if I encounter any problems, I'll come back and update my review.
