The slip - on Moonie's shoes are made of silicone. It is very durable with flexible, soft and extremely light material, that is very resistant to compression, squeezing and abrasion. The shoe insole is removable and you can very easily keep the shoe clean (get rid of sand and pebbles from the beach). The strap is adjustable and in order to ensure a better grip of the shoe on the foot, we can put it on the heel.
