I've had rubber half soles added on my blake 30 cropped jodhpurs which I wear as an everyday beater shoe. I had it done by Classic Shoe Repairs in London, who were recommended to me by the YSL Bond Street store, and who do the Bond Street store's re-soles etc. They also do a lot of work for other high end labels, and I have to say they did a great job (I've had rubber half soles added by other places before, but they made it look really sleek, and they're staying completely stuck whereas others have started peeling a little at the front with wear). Mine are holding up fantastically considering what I put them through, and I anticipate being able to replace the rubber half sole and heel at least once before a full re-sole. I tend to be hard on soles around the toe, so having the rubber added is a necessity for me, otherwise they'd hardly last five minutes.
