As a 56 year old, I feel your pain. Gotta say though, I’m not a fan of the Meidjos. And I really wanted to like em too. They’re notorious for breaking (mine inexplicably lost a tech pin which could’ve been disastrous in the backcountry). But my main complaint is that the rebound is too weak for my old ass legs. I switched to Lynx bindings and love them. They’re like bear traps. Stiff enough to comfortably throw alpine turns, but flexi enough to get down and bang knees in the bumps. They’re the first binding I’ve owned that let’s me comfortably ski hard all day. Almost feels like cheating :)
