Give your toes a little relief from icy winds without the hassle of full blown shoe covers in the Castelli Toe Thingy 2. Much like their predecessors, these handy covers slide neatly over your toes, securing around your cleat with a rubberized fabric for surefooted grip, without the excessive warmth of booties that leaves you with a case of hot-foot. Instead of giving full foot insulation, the Toe Thingy 2 gives coverage just where its needed, providing a nice barrier between your little piggies and the cold, whipping wind outside. Castelli's Toe Thingy is made from durable neoprene fabric. This material not only provides insulating warmth, but it also blocks water and wind on the most sensitive part of the foot--the toes. The Toe Thingy is secured to the shoe by an aperture that encompasses the cleat, and to resist rips, tears, and general wear, Castelli included a silicone print on the Toe Thingy's underside. For versatility, Castelli recommends using the cover alone on mild days, and as a layer between your shoe and full shoe cover during nasty weather.
