Are the crumbling soles made of rubber Prentice? This seems to be the case with so many boots these days. My ageing but still good boots have leather soles and heels, which can be repaired if necessary. Two pairs (same style, different colours) came from House of Bruar, who sell online. Other than trainers, I refuse to buy footwear with rubber soles.
Yes they are made of something manmade.It is true that they do not get much wear, the Winters in London have been so mild in recent years, so have been sitting in the cupboard, degrading.They are Hotters, about ten years old.
Thank you all for responses I shall do a lot of looking around at these suggestions.
