The Icons are designed with premium full grain leather uppers and rich calfskin detailing. The uppers are completely waterproof and resistant to stretching, but they also still allow air to circulate throughout the inside to keep your feet cool and dry.
4 of the Summer Series' styles have mesh uppers that enhance the shoes' breathability and that also stretch to give the feeling of a custom fit (#98951, #98975, #98968, #98854). The remaining 3 styles feature full grain leather uppers that provide excellent comfort, durability and breathability, as well as some water resistance (#98944, #98899, #98842).
