For new snowshoers and those looking for more comfort on their snowshoe excursions, the FLEX TRK offers the perfect opportunity for value-conscious buyers to have all the technical advancements found in the FLEX Series at an affordable price. With FLEX Tail, 3D-curved Traction Rails, gender-specific Compact Design and the QuickFLEX binding, the FLEX TRK has it all. Tubbs understands that better biomechanics and ergonomics are just as important to the beginning snowshoer, which is why we created the FLEX TRK. In packed or variable snow conditions the FLEX snowshoes are appropriate for all weights. In powder snow conditions the mens' models are best up to 190 lbs.
