Well, what can I say? Got this as my local shoe repair said he could do my boots as they were moulded! As the boots cost me a reasonable amount I thought what can I lose if I tried to do it myself, as my grandad used too? It worked! Ok, could be tidier (lack of experience!) but as they are walked on I dont really care! Got another year or two out of them which I wouldnt have done!) Would do it again, especially as a fraction of what it wouldve cost me at the boot menders! Well worth the cost, give it a go what have you got to lose and you have lots to gain! Next time will trim when stuck on I think, as they do in a shop, (ok they have a machine but a sharp tool and steady hand should do it!) Last time I trimmed before it was stuck, so will try it both ways and see next time. Not for those who like 'perfection' unless you have an expert to hand but with practice-who knows what result will be?
