The shoe insole has no arch support. This is a surprising lack for a shoe described as a Cross Trainer. I'm just using it as a casual everyday walking shoe, but the lack of arch support is still noticeable. My feet do not feel level in the shoe; they tilt inward and I'm sure over time the shoe uppers will 'spill over' the sole. I'll see if arch supports will make them feel 'normal. I will keep them but will not buy them again and do not recommend them.
