In reply to sabostar:
I can highly recommend this shoemaker. https://www.deschoenmaker.nl/#/schoenmakerij/
I got my new bought Lowa Tibets back a few weeks ago. I had the same problem: rubber edge, goretex sock, and a very stiff shoe anyway. But I always need a lot of extra space at my toe (hallux valgus).
You indicate on your shoe where exactly the space should be, how large the area, and how far it should be stretched. Done perfectly. Everything arranged by email and post. This shoemaker also carries out repairs for the bigger outdoor shops in our country. It is the right address... only it is in the Netherlands. Kind regards, Willem
