My single biggest complaint from the "big name brands" (Adidas, Nike, etc.) that make casual running shoes is that the toe box feels like it was made for soccer or ballet. These shoes completely fix that problem. I consider my feet somewhat narrow in the mid/arch area but wide at the toes/ball area. These shoes have fit me perfectly from Day One. The mesh is super breathable and great for warm weather. But I will have to find a second pair of similar shoes for cold weather; they will provide no warmth in any sort of cool/cold weather.Again, I'm an inexperienced new runner trying to keep my middle-aged self in shape. But I thought I would point out that while these shoes have nice comfortable cushion throughout the sole (and thus I love to walk in them too!), they tend to make you run with a "mid-strike" or ball/toe strike type of gait. It doesn't feel like there is enough cushion in the heel to run with the heel strike gait I'm more familiar with from my younger past. But I must say, I am picking up the new style pretty easily, and I don't seem to finish my runs with calf and shin aches I may have had in the past.These shoes to me are just all-around comfy, and instantly fixed the long-standing toe box crowding problem I found in many other shoes, so I'm happy to give them 5 stars.
