Q Ive developed a recurring blister between my big toe and the one next to it. Ive tried taping up the area and also using petroleum jelly, all to no avail. Its now making me miss training.A As youve discovered, petroleum jelly is not durable enough to overcome the mechanical stresses that occur between your toes. And while taping didnt solve your problem anyway, it may also have restricted circulation and the movement of the most important joint for propulsion in the foot.
There may be a number of reasons for your problem, but my first suggestion would be to separate the toes with an inter-digital wedge. I have treated patients in this way using Ortoform, a putty-like material which dries in minutes into a rubbery, custom-shaped removable insert. It works well, and any good podiatrist should be able to provide this product and mould it for you.
