Yuk that looks infected mate. Shame we don't have smellavision on the forum.

Sea water will work wonders if you spend enough time in the Sea. If not, then you need one of them foot spa's (or bike oil draining pan

) and some bath salts, you can get some in Epsom

Then stick you feet in that while watching the moto gp. And yeh get yourself a pair of Croks you want to let the air get to it so it don't remain moist and manky.
You can also get plasters with a gel type substance to help draw the puss out too, but I don't think your at that stage unlike my ankle when that was an open wound. Now that was proper rotten and smelt like death and should have had some maggots. That was when they stuck me on IV antibiotics that left a nasty metallic taste in my mouth. I could see what was left of the bone, tendons and everything before the flesh grew back and the wound closed up.
