Love the shoe, and the SOLE has withstood the test of time of me exercising ~6 days per week:

- Running 25-30 miles either on a treadmill or concrete sidewalks (I know... ugh)
- HIIT workouts
- Moderate strength training

However, I have pretty pronounced ankle pronation, which has resulted in the outer mesh/fabric of both shoes in this pair to rip after 7 months of use.

Personally, I find them comfortable -- for both walking and the exercises noted above -- with a perfectly sized toe box. I'm coming from Vibram 5-fingers and I personally prefer these Vivobarefoots.

7 months for $135? I'm neither here nor there about it. The soles still look immaculate, though.
