Our new running shoe has already made it mark.
When word leaked out that Tred 2 was designing a running shoe, we received thousands of orders long before the first pair was manufactured. We're proud that our reputation for quality athletic shoes is so wide-spread. And we believe the Zephyr will even surpass everyone's expectations. To build it, we studied the best features of today's running shoes -and improved on them. For example, the sole is our patented two-layer "Honey-comb Pyramidal System." On the surface are pyramidal studs -for maximum traction and durability on all surfaces. Beneath is the honey-comb foundation -for ideal lateral support and stability. . The Zephyr will surround your feet in cushioned comfort. Try it on at sporting goods stores, specialty stores and leading department stores throughout the country.
