I was a little nervous buying a pair of shoes with no laces because I wanted my feet to feel secure right now;  Im wearing a knee brace on right knee and for some reason tightened laces makes me feel less likely to fall.

Support:
I was super surprised that although they aren't extra snug on my feet I never feel as if the shoe is about to come off and Ill lose balance.  I feel stable and each foot plant is confident because they have really good traction.

Comfort:  They feel like you're walking on clouds all day.  If clouds felt like a nice thick rug.
