Familiarity: I've put it through the wringer
This boot is super fun to ski on, and they look really cool. they work well for cruising groomers, or steeps. For XtrEmE skiing you might want the custom or the T race. The boot is very warm and the boa system is quite effective! The boot skis fine, but the durability of the plastic is extremely questionable. I have cracked a pair of these in the back to the right and left of the ankle on both boots, and so has my friend. My same friend also cracked the new pair that black diamond supplied him with in an insane fashion. He cracked the front of the duck bill off, and the whole lower inch of the boot started to peel and crack off, and you could stick your fingers inside and touch the liner. That same day he cracked the other boot in the back about 6 inches. His and my boots absolutely blew up!!!! Black diamond did indeed replace the boots for free in about 2 weeks, but it is not all worth the hassle....You might as well buy scarpas and save yourself an extra 2 weeks of skiing instead of waiting for a new pair of boots. T1s or T race.
