Great shoe, however I think I am going to try cumulus or nimbus asics next time. I put about 500 miles on the equation 5s and it really beat the heck out of them. I'm up to 50-60 miles a week and I'm not sure the Equation's really hold up as good for that type of mileage compared to the Kayano's and the higher end Asics. That being said for my wide feet (4E) these guys are comfortable as can be! I raced a half-marathon first time wearing them and my feet felt great. I may just grab another pair or try the 7s if they are out in a few months and wear them as racers this winter, since they are lightweight and 4E flats are basically non-existant.
