Great shoe
Love this show and the shopping experience with Marathon. Fast shipping, easy online purchase. I use this show to walk 5 miles daily & another pair of Hoka ATR 6 for work in the hospital.

Get a shoe that can do it all! (staff)
I love that I can wear this shoe on both trails and roads. I don't have to worry about my footing on rocky paths or even slush when I'm out on a run. The shoe runs a bit narrow, but that is typical with me for a number of different Hoka models. Otherwise the sizing is pretty spot on! I'm also hoping to take these on a number of hikes in the Northeast and through Montana as we get closer to summer. I'm also a huge fan of the colors on this model, they are all so great, you can't go wrong!

Great for taking on your next Challenge [Staff Review]
I love my new pair of Challengers! They're super soft, have good traction, but are still smooth on the roads too. The fit is a bit long. This is typical for Hoka but I could have happily gone down a full size from my normal size. The colors are great too!
