Hyperflex - 3mm VYRL Square Toe Boot


Using the VYRL CRYO 7 and VYRL 5MM boots as inspiration, Hyperflex designed the VYRL 3MM boot using a soft and minimal design approach. Thin and light weight are the predominant words here. The boot provides all the necessary warmth while maintaining the best barefoot feel available.
