I've developed a bunion, so I need to use toe spacers (Correct Toes) that make foot wider across the toes. Without this change in foot geometry I get a blister in 2 miles. For summer I've started to use vivobarefoot toes that work OK. Everything else I've tried gives me blisters — e.g., Keen boots have a wide toe box and don't work. For winter I have several expensive boots that I like, but they're now too narrow in the toes.
So, the question is can these boots be stretched enough to be usable. Should this be done only by a cobbler or can I use boot stretchers like this:

The boots are:
Heavy leather Raichle hiking boots, great for winter/snow/ice.
Warm leather insulated XC ski boots (NNN BC bindings).
Plastic mountaineering boots with insulated leather inner boot (Raichle)– perhaps ski shops can stretch the plastic outer boot?
If it's a bad idea to stretch the leather boots myself, can anyone recommend a good cobbler in Mass or NH?
