Vertical World is kind enough to give some discount on their resole service for all the Everest Challenge participants.
Its R275 for re-sole and re-rand. Normally its R375 for a re-rand.
Otherwise I would suggest glueing some spare bicycle tyre onto your shoes' toe to protect against the concrete. The routes are easy enough. Well, that's what I'll be doing.
We'll probably send a couple of pairs through after Everest Challenge. Check out www.verticalworld.co.za for more info
