We torn a set of HL 360s on the rear gorilla pull completely apart..I took them to a tailor and she sew'd black leather kinda like a band aid on front and back of rubber.Its held together for 3 years (granted they're on my girls board i carry on,which rarely get used)
But I've tried them on myself and they still work fine. Just a little more lube to get your heel in over the bump, but riding is unchanged...
IMO it was a great fix for a grand total of $12
to save a pair of bindings...
If they are your primary set you need to kick down a buy new ones...Cause although my fix is ingeniuos its not a remedy.
