I am a senior runner, putting in about 16-20 miles weekly on the streets. I really need to have a well cushioned shoe to keep these old bones from getting too sore, and this shoe really does the job. I've also run in the Gel Cumulus, which is less cushioned than the Nimbus, with the biggest difference being in the forefoot, but I prefer this shoe. If it can keep my body from being a mess, it will probably be fantastic for the younger runner.

In order to give you a fair comparison, I'm 5' 11" and 165 lbs. If you're heavier, then you'll have a different experience, but if you're similar to me, this shoe should do the trick.

I wear a street shoe in a 9.5 American or 42 European and need a 4E. I have a wide front foot but a narrow ankle, like an inverted "V." Asics' are designed perfectly for that type of foot shape. I take this shoe in a 10 American, 4E. I probably could get away with a half size larger, and may try it with my next pair, but you'll definitely need at least a half size larger than your street shoe. Go to the mall first to try a pair on before you commit to a size, or try Zappos and order both, then return one. Shipping is free both ways.

One last note. While Amazon owns Zappos, these shoes are almost always less expensive on Amazon. I don't quite understand the reasoning behind that, but the difference is often $20 or more, so be sure and shop both sites.

Happy running, and stay safe out there!
