I bought these and a pair of tennis shoes because of knee pain. I can't even wear house slippers, the way these are made make it possible for me to be mobile with less pain.
I put them on as soon as they arrived and they immediately felt so comfortable. I have bone on bone situations in both of my knees and these feel like they really do help redistribute my weight while standing. I feel comfortable when standing in these and minimal pain. I'd recommend getting these with a pair of the walking shoes for comfort in daily wear.
