with my old motorbike racings leathers what i did was got in a warm bath wearing them. it supples the leather up a bit more and then they are better to wear. try this mate....they are leather and i did it with a pair of Â£250 bike boots before and it worked. just make sure you let them dry out naturally else you will ruin the leather and it`ll start drying out
If the leather isn't left to dry naturally, it goes harder than before and is basically unworkable. I'd agree with Praetorian for the safest option, always worked for me. Failing that get someone else to wear that for a fortnight or so
Fill em with hot water from the bath tap, and leave them to soak overnight...Next day, empty them out, stuff with newspaper for an hour or so to remove excess water. Wear em, and go for a long long walk. Wear them as much as possible while they dry naturally. If you have goretex socks, then jobs a good un....
They'll mould to the shape of your feet. Just dont place them next to a radiator to dry them, or the leather will set rock solid, and be worse than before you started.
