To settle the nerves I busied myself happily breaking the first rule of running...
Never get new footwear just before a race. Never ever. It will end tears.
But I'm choosing to belieive that there's a loop-hole in this running law (another trusty mental technique here) that applies to those of us whose footwear consists of rubber flaps tied on with string, especially if said flaps have got to the point where they've been colonized by what feels like a slippery algal growth that thrives on foot sweat.
Luckily I had some spare pieces of Vibram soling so it was a simple matter of tracing around my old huaraches and cutting out the new ones...
Punching the lace holes...
Making a recess for the bottom lace knot...
Lacing them up (that's the old pair festering on the right)...
And we're ready to race !
