Forearm Crutches

I am still getting used to them, but I can already tell they are a big improvement over my previous solution of using two regular canes. I love that they stay on my arms when I need to stop to lift something, etc. My only concern is that the description of the crutches said they were good for up to 350 pounds, but the canes themselves are clearly marked at a maximum weight of 245 pounds. At 220 pounds, they are within my weight, but I worry that if I'm carrying something in a couple of bags that push my weight over 245 pounds, they may break on me.
