Our product  Made of 100% natural rubber, our products are completely safe for the consumer and the environment. Each pair has to go through a waterproof test, which consists of injecting compressed air into the boots which are then submerged in a pool of water. We add a special hidden insole to make the boots stronger and to avoid any discomfort under the feet. Elvetik® Swiss Design Rubber boots are presented beautifully packaged in 100% recyclable card. Each boot is carefully positioned and presented ensuring lasting protection during transit. Inner packaging further protects each boot to ensure a long, colorful and comfortable life.
