Good upper though I wouldn't go sock less because of a seam on the side. No blisters to note.
It's my first zero drop shoe and it took me a month to build up and be able to run a good long distance. I should note i have low arches and it feels great to have a shoe without the unnecessary arch support. Replacing the insole with a more cushioned one from Gorun Ride helped me transition to where I am now. Has really helped my form to run mid/forefoot. I'm amazed how the shoe disappears as you run. it's that light. Only bad thing to note is the unfortunate wear on the pad on the outsole over the ball of my foot on both shoes. If they had rubber on that specific pad like the do on the big toe area I'd give it five stars. Very good overall by Skechers. They're doing great work In their development.
