So first up on our new “How can I repair this?” feature, how can I repair a pair of leaking trainers/sneakers?

I’ve got a pair of canvas trainers that I love – they’re like the ubiquitous Converse ones but No Sweat ones so sweatshop-free. I’ve worn the hell out of them for about five years and now they’ve both developed leaks in the sole – little tiny cracks/tears around the ball but on one of them the upper has come away from the lower slightly at the back too. I’d rather they didn’t become just fair weather footwear – so how can I fix them?

If they were hard soled shoes, I’d take them to a cobbler to be resoled but am not sure if they’d fix soft rubber soled trainers.

What about at-home fixes? I remember reading somewhere that someone suggested using silicone sealant to fix a similar sneaker leak – anyone tried that? Any better alternatives?
