I have really bad knees and was looking for something that offered stability and cushioning when walking. I usually buy inexpensive sneakers like DR Scholl's brand every few months, but thought I'd go for something more expensive for a change expecting it to be longer lasting and to offer more cushioning. Wrong! These were almost like walking with a wooden board tied to the bottom of my foot. They were unyielding and stiff and offered no cushioning. At first I thought it was just cuz they were new and needed to be broken in ... but after wearing them 5 days a week to work (8 - 10 hrs per day) for 2 weeks, I am seeing that they are still just as stiff and uncomfortable as the 1st day. They made my feet hurt just walking a few hundred feet and thus made my knees hurt worse than normal. They may help others with different problems but for ortho-arthritic knees, they are not a good choice! I won't buy this brand ever again.
