Great So far
Customer Rating
I've only used these shoes a few days. Mainly walking on the treadmill an hour a day. Very little running. They are much more supportive than less expensive ASICS shoes and more expensive Nikes that I've used in the past.
these are IT!
Customer Rating
I'll be honest, I'm overweight and needed a good pair of comfortable running shoes to get back into an active lifestyle. I haven't had a good pair of running shoes in years, so with the help from a friend who runs actively and some try-ons at the local runners shop I can definitely say these shoes are the most comfortable and supportive out there in this particular price range. They have an amazing comfort about them. . . even just sitting down your feet breathes with ease. They are very lightweight and have a very steep arch support which I found to be extremely comfortable. The gel heel of the shoe is also very bouncy and cushioned to help provide a lower impact running/jogging/walking experience.
Go Asics
Customer Rating
When it comes to a running shoe go with a company that specializes in making running shoes. Buying a Nike running shoe is like going to a Mexican Restaurant for a steak. They may be able to make it for you but that doesn't mean it'll be good. Asics makes awesome running shoes and these GT-2170's are no exception. Go Asics!
BEST RUNNING SHOES EVER!
Customer Rating
It would not surprise me if Runner's World chooses this pair of running shoes as a Best Update or simply the Best Pair of Shoes the next time they review running shoes in the Spring 2012 issue! I got Plantar Fasciitis in both feet and a painful heel spur in the right. I run a lot and most shoes seem to be uncomfortable even after around 100 or so miles (usually between the first 10-15 runs for me). I've always looked for either Motion Control/Cushioning support and owned pairs of running shoes from Brooks, Saucony, Nike, New Balance and even previous Asics models to name a few that I've tried. My size 12 under pronating feet to go along with my 6'2" nearly 200 lbs frame always seem to hurt as well my lower back and recently around my knees area on both legs as well. Looking around for a new pair, I was going after the 2160s but just didn't like the feel for them. Great shoe- don't get me wrong- but just wasn't for me as I wanted more cushioning than what the shoe was offering. However, I've discovered these 2170s next to the 2160s. Without any doubt, I can honestly tell you that I now have my best pair of running shoes I've ever owned. There is plenty of gel, foam, cushion and yet a firm-like support structure throughout the shoes that I can't recall ever feeling and now makes me want to run further than before and has got me feeling the joy of running when I first started to get into the sport. Even the sides of my feet are feeling good after a 10 mile run this morning. If your New Year's Resolution is to get back into shape and you want a good pair of running shoes to go running, jogging or brisk walking in- you can't go wrong with these shoes in my opinion (unless you are looking for minimalist shoes like 5 Fingers or Nike Free) as these Asics 2170s have the perfect combination of both cushioning and support structure I have run-around in during nearly 15 years of running.
Asics Most Comfortable Ever
Customer Rating
I LOVE these shoes. They're got more shock absorbtion than the GT-2160 and earlier models. I sing a happy song everytime I take a walk in them. Not crazy about the colors/styles but as for the construction of the shoe, it's unsurpassed.
