Very nice sneakers that I bought for my sister because she has been having knee and walking problems.  These sneakers fit the bill.  She says they are very comfortable, very light-weight (no stress on knees) and non-skid.  We bought the charcoal, black and blue and they are quite attractive and haven't been showing any scuffs or dirt so that is an added plus.  If you are considering them we do highly recommend these.
