Hi all, I've been scrambling and climbing in my much loved La Sportiva Boulder X's for a good few years now and already paid for one resole. However, recently the rand area on both toes has started to split revealing white wooly fabric. See picture:

Bearing in mind how battered the shoes are I don't think it's worth paying for a repair but the soles still have plenty of life in them. Is there anything I can apply to the split (I'm thinking glue/bitumen/molten plastic etc) as a makeshift fix to stop them splitting further?
Thanks for any help
