These shoes are awesome. They do run small though. I am usually an 8.5 but like to order running shoes in a 9 for extra toe room when running down hill. I ordered the 9 and it was more like an 8. I had to go up. My feet are narrow, and they fit well without having to synch up the laces too much.The elastic sock around the ankle has a seam that hits right below the top rim of the shoe. I wish it went all the way down to the footbed to eliminate the odd feeling of the seam there. Until you get used to it you keep feeling like your sock has slid down and want to try and pull it up. But otherwise they are great. The insane traction from the rugged sole is great for trail running and the color is fun. The support is good and the arch is not one of those types that feels like a roll of quarters under your foot. Very subtle arch, and it is actually in the right place. If you need a strong, high arch support these might not work for you. But I have a flatter foot and the low arch is great.
