TYR Fin Boot Experience the thrill and adventure under water with the TYR Fin Boots. These boots are made of the revolutionary new nylon 2-neoprene polymer which is known for their massive strength and elasticity.

In addition to it, the flat lock stitching also increases comfort as well as the strength. They are available in four color-coded sizes and variety of size from small to x-large that will surely match your needs and style. Experience comfort and style with the TYR Fin Boots.
