Comments: Ran in my orange boots yesterday for the first time, they are incredibly smooth and stable for a minimalist shoe. The ride was simply fun and explosive. I have not mastered the speed laces yet, but I will say for a shoe that you can pull on and off, the fit was just secure enough. Altra's online customer representative advised me to upsize from my street shoe size 10 to Altra size 11, which was definitely the right call. I have tried nearly every leading brand of minmalist shoes, Altra has the balance right with The 3-Sum.
