I recently went to their website to see if the new products were out yet, and they are!!!! I'll be sure to get a new pair soon! Here's the links to the different models, and a little about each....

The KSO is an all-new design with thin, abrasion-resistant stretch polyamide and breathable stretch mesh that wraps your entire forefoot to “Keep Stuff Out.” A single hook-and-loop closure helps secure the fit. Non-marking Vibram TC1 performance rubber soles are razor-siped for a sure grip." *
"Whether ChiRunning in colder temperatures or crossing a stream with your kayak, the new FiveFingers Flow provides comfortable barefoot protection. A 1.2mm Neoprene lining and 2mm EVA footbed provide the thermal insulation and protection. And our new GM50 performance rubber (available only in black) is razor-siped for added slip resistance over a variety of surfaces."*

A thin, abrasion-resistant stretch polyamide fabric fits low on the foot—for comfort and quick drying."*
"Some have called FiveFingers Sprint the most versatile footwear they own. Adjustable hook-and-loop closures cross over the instep and surround the heel for a personalized, secure fit. A thin abrasion-resistant stretch polyamide fabric follows the contour of the foot for comfort. And a flexible, non-marking TC1 performance rubber sole is razor siped to enhance grip over a variety of terrain."*
