We have been using Happy Little Soles for 4 years, our son has a very high instep - after spending a small fortune with "trusted" childrens shoe companies who assured me their shoes fitted, and end up with a little boy who's socks where stuck to his shoes from weeping blisters, I decided to search the Internet, where I learnt about the real benefits of bare foot walking, and that lead me to Happy Little Soles. There filter includes suitable for a high instep, and we have bought all our son's school shoes, trainers, sandals, wellies and paddlers from them ever since, with 100% success rate. I had always believed you should only buy shoes that had been fitted by some one with training, I now know that if you follow the excellent guide lines on Happy Little Soles website not only do you end up with a well fitting pair of shoes, I'm protecting my sons joints etc in the future.
