The Animal boot now features a 100% natural rubber overlay, molded to the original Animal Overlay shape. This results in a snugger, more comfortable fit than ever before. The Front Animal boots is designed with a THICK rubber overlay for increased front boot control, while the Rear Animal Boot is designed with THIN rubber overlay for less back boot control to compliment front hardshell boots. Now with a softer durometer, heat moldable EVA tongue and heel, you'll have the rubber boot feel you want with far less overall weight. In addition, the new soften, thinner, brushed EVA footbed increases comfort and is designed to equalize skiers' front and rear foot height when using hardshell boots.
