I've just made my first pair of Barefoot Ted DIY sandals (using their 4mm rubber sheet), and now looking forward to my first run in them tomorrow. Very good service from the Luna Sandals website, I followed Mandovark's advice and ordered two pairs with one P&P from the USA.
I'm doing almost all my running now in sandals, using shoes only for races, although that may change soon!
I've already converted one running friend to using sandals, more to follow maybe?
