I gave in and bought a pair bc the girls at work were raving about how comfy they are. Omg! I walked the dog tonight in them and it was like stepping on the plump tiny asses of pink cherubs while baby unicorns sang Ave Maria and sprinkled rose petals in our path! In all seriousness, worth all the hype. Zero impact on my horrible knees and it made walking a pleasure instead of the painful experience I usually have to psych myself up for. Get some!
