I just mentioned to a friend who's son is also doing the expedition this weekend that my son will be wearing strong comfortable trainers and she was shocked and appalled! As a family we do a lot of walking and we all wear trainers as I have always hated walking boots. On the bronze trip all the kids with walking boots ended up with horrendous blisters and tired feet, whereas my son's feet were fine. The weather is going to be dry but I am now second guessing my decision as it does say walking boots are essential on the kit list (as it did on the bronze one).
