Closeout on the original Fischer Rollerski boots. RCS boot without the outside lace cover. This means the boot, which incorporates many of the features of the World Cup favorite Carbonlite Skate boot, is lighter than the winter boot with the same Xcelerator NNN sole and the instep buckle. It lets air flow around the ankle and the nylon mesh of the outer boot moves moisture away from the feet. It also has the anti-microbial lining that helps with that old boot aroma. The carbon fiber ankle cuff has the same canting feature as all the top end Fisher skate boots. Works with NNN and Prolink bindings. Let us know if you want us to take out the insole and send you measurements for the size you're interested in.
