I am looking for carpet mainly for children but also for adults to allow special support/training for flat feet. So the carpet needs to have 'bumps', so when stepped it can allow special pressure on the arches to strengthen the muscles. The carpets need to be designed in playful manner so they have only therapeutic purpose but would also decorate the room. Creative and funky designs would be great. The material of the 'bumps also need to be carefully considered as continuous pressure will be applied.
