Victoria Boys' Walking Trainers - Lightweight Comfortable Sneakers for Kids, School, Play & Outdoor Activities

These shoes are pricey -- but very cute, and nicely made with cotton canvas and natural rubber. There is minimal synthetic material as far as I can tell. Natural rubber usually has a strong smell, which could be a little off-putting to a young child, so the designer of this shoe did something really clever -- they scented the rubber with something like strawberry scent. It was a little strong at first but my daughter found this very delightful. It remains to be seen how long they will last, but the fit is comfortable and they stay on well with an elastic gusset.
