Ton, just took a quick peek at the flexyfoot site, you’re just within the weight limit for the ferrules so I’d seriously recommended some, for you too, ahsat. About 25 quid iirc, maybe extra for delivery. As metcalt said, be careful when out and about at this time of year, again the flexyfoot is your friend. I bought some for mum as well and the sure footedness is as big a boon to her as the comfort they offer. I know I sound like I work for them, I don’t,I just discovered them whilst trying to find ideas to make my crutches more comfortable but I do think they are genius. In fact, I’m not on my crutches at the moment so I have a pair of well worn flexyfoot going if anybody wants a free trial. If you like them and decide you want some just post em back to me. Winter’s coming and I want to start exercising again so I may want to call on them at some point but happy to let them go to someone who could do with some right now.
