If you want a boot that delivers race performance coupled with one of the most comfortable out of the box setups around, you've found it with the Lange Men's RS 110 Ski Boot. The control fit liner gives you plenty of foot security to keep your dogs from slipping around, even on those warm spring days when things start to sweat. To help you find a comfortable fit, and to prevent muscle fatigue, Lange added an adjustable forward lean as well as adjustable canting. The 110 flex gives you plenty of power, but won't leave you feeling like you need to hit the spa at the end of each day. Though it's doubtful that anyone's going to think it amiss if you keep hitting the hot tub every evening anyway.
