The basic concept of BILLY footwear is a zipper that runs along the side around the entire shoe, allowing the upper to be fully opened and open. This way, the user can freely place his foot on the insole. Then, when the zipper is pulled, the shoe closes and secures the wearer's foot. It's easy. That's easy. This concept makes the shoes perfect for children wearing orthoses, because we can check if everything fits well and then fasten the zipper, without the hassle of stuffing or pressing the foot while putting it on.
The unique feature of this model is its reaction to sunlight. In the shade, the footwear remains white, while the sun turns it purple.
