Whats in the box:Pair of Finis Z2 Zoomers Kid's Fins
With its comfortable fit of 100% Long Lasting and Durable Natural Rubber, the Z2 creates a soft and secure fit and inhibits hyper flexion. With its short blade, Z2 Gold Zoomers encourages shorter and faster kicks while experiencing just enough propulsion through the water. The Z2's Forward Propulsion Hydro Channels efficiently propels you forward. The fluid separator located on top of the fin, allows your foot to easily slice through the water while reducing fatigue on the down kick and quads. Whereas the Flex Box, located on the bottom of the fin, helps you catch the water on your up kick, targeting and strengthening your hamstrings and glutes. Sizes available are: US Kids 7.5 to 8.5, 9 to 10 and 10.5 to 11.5 (EUR 24 to 26, 27 to 28 and 28 to 29).
