Walking boots: repairing cracked leather

[mmmarmalade]

The leather is cracked across the toe - it's thick leather and I can't feel the crack on the inside so it's not right through but there are SO many leather products - can anyone recommend something you've used for a similar problem? I haven't worn these heavy boots for several years - I've just been using lightweight walking boots - so they've been a bit neglected since I last used them, stuck in the utility room - I've used some Renapur on the boots (which I had for a leather bag) but the cracking looks like it could do with filling with some kind of glue or paste. Suggestions?

TIA

This is the cracked area FWIW

I have asked DH, who used to fit and sell walking boots in an independent outdoor shop. He's not aware of any leather filler type product.

Actually, try Shoe Goo. You can get it on Amazon, but I can't work out how to attach a link without also including my account details and credit card details!

Not a filler but I use dubbin to keep my leather in his condition and waterproof. Might that work?

Actually, now I've seen the photo, the cracking is not as deep as i'd imagined. I'd just use a load of dubbin or traditional Nikwax or something thick like that.

@IbizaToTheNorfolkBroads well I have used Nikwax in the party but tbh I've not worn these boots since before COVID in 2020 and they've languished in the utility drying out - I didn't have any Nikwax so used the Renapur leather balsam - I think I'll just see how it goes - I honestly can't remember if they were letting water in - I've recently seen leather glue which is supposedly as fluid as water - not thick and gloopy - that I was tempted to try. The boots are about 20 years old - good Scarpa's and had previously been looked after - they probably wouldn't have cracked if I'd cleaned them up and treated them the last time I used them.
