| Birkenstock for knees, who would have thought it? The anatomically formed, shock-absorbing polyurethane foam cushion does for knees what the sandals have done for the feet - evenly distributes body weight to reduce damage and pain to joints. Use outside or inside, whenever you need to be on your knees for an extended time. Experience less stress and lower the risk of damage and pain. And if you happen to leave it in the garden, the bright orange is hard to miss. A great gift for yourself or anyone who has a green thumb. 15 x 9 1/4 x 2 . |
