I'd stay away from the Cosmos. Scotts version of the boot seems like a winner until you put a few (literally only a few) hours on it and it falls apart. Two patrollers I work with have them and both have had nothing but trouble with less than 40hrs on them.
1. Ankle hinges exploded. Not only that, at the local shop the tech confused one of them with a third unknown person having the exact same problem. Go out for a walk and lose your canting adjustment hinge. Three people in as many weeks with the same identical failing on the same brand new boot.
2. Clasps exploded. The wire spreads and releases on all but the bottom toe clasps. Both boots on both pairs are currently held together with medical tape or they wouldn't stay on a pair of feet.
3. Tongue exploded. Both tongues are cracking/ripping at the flex point on both pairs of boots.
So a nice looking, comfortable & lightweight boot that will leave you stranded on the first, second or maybe third run. Eat the few extra ounces and get something reliable. Their horror show on two separate sets of identical brand new boots, doing light duty walking and skiing, has sold me on never picking up the cosmos. Less than a week in they started having problems and they don't seem to be stopping. Then finding out at the ski shop that others have identical problems? Something smells like garbage too me.
