Customer Reviews

Comments: I was running the Asics Nimbus 15 and tried the Gel Noosa Tri 9 and love it! The Nimbus is still one of the shoes in my rotation but I think when they wear out, I'll go full time Noosa Tri 9. Very lightweight and comfortable, easy ride. Asics has knocked another one out if the park with the Tri 9!! Thanks to Running Warehouse and Asics for an awesome job from a very satisfied customer.

Comments: Admittedly I am a big fan of Asics, my past 3 pairs of running/training shoes have been Asics trail shoes. So I was slightly hesitant to jump into a "Tri" shoe. Until I used them the first time. I have been doing much more weight training since I broke my foot and was looking for a shoe with more breathability than the trail series. These are insane in that regard. I feel like I'm just wearing socks and can feel the breeze through my toes as I walk. Best shoe I've ever bought and I realize it is all down hill from here. Get some, you won't look back.
