In reply to Dan Bailey - UKHillwalking.com:
Definitely a departure form their other boots! I found that the Kentos exerted too much downward pressure on my MTP joint (big toe) and after 30 minutes, couldn't take them off quickly enough. Shame because I love their other boots.
@OP, Kento 47 was spot on for me, forgetting the above issue. I'm a 47 in Scarpas but cannot wear La Sportiva, too narrow.
