I can appreciate this, as Burton's toe/heel adjustment is far from the best. With no adjustable heelcup, you're limited to what the disc can do since the heelcup is a set size--and a pretty long one at that.

Burtons fit "longer" in this way. I'm also in a medium binding, but with size 10.5 boots--which is basically the biggest boot you can comfortably fit. However, my boots are close to perfectly centered over the board in the middle hole (maybe a touch heel heavy). From there, there's only 5mm toeward or heelward on the discs. So actually, these medium bindings are sized for 10 to 12, in terms of length (if my calculations are correct).

All that being said, I'm a little surprised you're that far off, as I figured you'd be pretty close to centered with moving them toeward. Are your boots particularly short? Are you sure they're medium bindings and not large? (sorry, not trying to insult)

 

Yeah it sucks, especially when your boots are around 10.5/11 us and you're riding the limit between M and L bindings.

 

Might consider a binding with an adjustable heel cup.

Size 9.5 boots on a mid-wide board should not have that much heel overhang.

 

It’s a K2 boots in Burton bindings issue. Burton boots are really rounded at the heals, so they prolly take that into consideration with the fit. You could easily ride a bigger size standard too.

 

I use to grind/round off the tread hanging over, but I haven’t done so in over a decade as footprints got smaller. But yeah, reflex adjustability is limited… I try to get it fairly even, but now I realize that I like my Toes a bit closer to the edge.

 

Damn Yes recommended a 151 for the business I asked about. Mobility in trees and general maneuverability cause I like to ride like the whack inflatable tube guy. Ha they said I could go with the 153 for more solid underfoot feel when bombing. Went 151 for playfulness and have not been disappointed on the Standard at all!

I’m gonna just except it as a comparability issue. Have only ridden a couple Burton bindings in my time on the hill. Am curious about Katana bindings. This does the job though with no heal drag today in thekinda snow that makes the place feel like powder soaked in water

Been eyeing the Dynamo 156.. saw one today at the rack lookin sexy af.. ran into the dude that had it and picked his brain. He was my weight and height and Loved it except for jibbing stuff. Gonna try to rent one from the local shop next week.
These 2018 Cartel bindings are pretty nice except for the de agh grip you can enforce with the hammock strap. Put a Malavita high back in them today and they ride much more complimentary to my feet.

Also went from 12/12 to 9/9 angle today… surprisingly comfortable and my carving control at ability to blast through terrain at a 19.5” stance was pleasurable. ✨

 

I have some rome dod that I would entertain trading if interested.
