Sooo comfy!! I bought this for my trip in Chile and Argentina where I would be doing a lot of hiking in various terrains. These were comfy right out the box. No need for breaking in. We did a ton of hiking and walking on my trip around South America and these were soooo comfy. These also kept my feet dry during the rain. It also kept dirt out of my shoes. Please note, I washed them in the dryer and now they're no longer waterproof. I'll need to look into buying a waterproof shoe spray. In regards to grip of the shoe for hiking, I'd say it has decent grip. The fit runs the same as my other Nike shoes. Overall, I'm super happy with this purchase.
