I have mixed feelings about the Millenial Crutches. The ergonomic design is great and it causes very little discomfort under your arms. The problem is that the hand grips are very slippery...don't even think about using hand lotion anytime prior to using them! They also are supposed to help propel you which makes these crutches feel like pogo sticks compared to traditional crutches. As a result, I got scared and did not use them much at all. Instead I purchased a knee walker which I highly recommend (can use your hands and keep your balance). Note: I had bunion surgery and could not bear weight on the foot for 6 weeks. Therefore, any type of crutch would have made my life fairly miserable. I'll keep the Millenials and try them again...I think.
