I have been running on the Exalt-2 shoes for 5-6 years.  The Exalt-2 is now hard to find so I thought I would try the Exalt-3.  I run about 3-3.5 miles per day typically 4-5 days a week so I'm putting approx. 15-16 miles a week on my shoes.  I run on either on pavement or a treadmill depending on time/weather.  The Exalt-3 feels pretty good so far, I have only ran wearing the shoes 3-4 times so far so I need to run on them more to give a more detailed review, but so far so good.  The toe-box seems to be a little larger than the exalt-3, but not too big.  My toes don't move around so the shoes feel good so far, but the shoe definitely seems wider than the exalt-2 felt.  My heel hasn't moved while breaking the shoes in so I have not got blisters on my heels so that is a good start.  I wear a size 10 and ordered a 10 and they fit perfect.  The size runs true to size.  The only thing I have noticed a little bit is my heels are a little sore after running in the shoes, which hasn't been an issue with past shoes.  I"m hoping it is simply because the shoes are new and after wearing them for a little more time that won't be an issue.  Hopefully there is a break in period.  I didn't have this issue with the exalt-2 model.  Before buying the exalt-3 I did some research and it didn't seem to be an issue regarding people's heels hurting on these shoes, but just do some research of your own.  So far I'm just as happy with the exalt-3 as I was with the exalt-2 shoes.  I have ran wearing Asics for over 10 years so you just cant go wrong if you do your research and get the right shoe for how you run.
