Do those boots have a smaller print than most boots?

I'd say get the larger size if you're unsure. I had to sell a pair of bindings last season because I didn't buy the larger size.

 

Go here, and hit the sizing button on the right side of the page. Rosa Snowboard Bindings | UNION BINDING CO. 2012/ 2013

 

Ummm ... The sizing chart really doesn't help, since her boot is a 5.5. According to the Union Sizing chart either a small or medium binding would fit her boots.

I've found almost all binding manufacturers sizing charts to be a complete waste of time for those who have boot sizes on the border of the binding sizes. They don't take into account the actual footprint of a boot, which can differ considerably from boot to boot. I'm not sure what a practical solution to this may be, but is certainly not consumer-friendly.

 

Thank you to the other people who replied. I ride the union atlas, and was about to introduce the brand to my gf, however the reply by union has put me off. If I wanted that kind of comment I would have gone to a shop in a burton hoodie and been treated like a gaper there instead.

 

Jesus, woke up on the wrong side of the bed much?

Get the larger size just to be safe, and adjust the binding to fit her boot.

/thread.

 

I just don't think sizing up is a good idea. If you can order a pair in both sizes, do it and keep the size that fits. Make sure you can return the pair that doesn't fit.

It'd be great of the Union's site had actual measurements that actually could be used to give people a better idea of how they might fit their boot, not just some arbitrary boot size, so they don't have to waste their time.

 

You neglect the fact that boots do not come in standard sizes. Some are slimmer, some are fatter. Some have a wider sole, some don't..

 

OP, if this is of any help I have the Rosa in medium (size 8 boot, 32 Lashed) and took some measurements for you.

These are all inside measurements of course. If the conversion from inches to cm is wrong, that's on Google, not me.

Widths:
-From the inserts of toe strap: 4 1/2 inches (11.43 cm)
-Most narrow part: 4 1/8 inches (10.48 cm)
-Heel inside highback: 3 7/8 inches (9.84 cm)

Lengths:
Heel loop and gas pedal are adjustable. Three settings of 5/16 inches (.79 cm) and three screw holes respectively. I'll give you what are set on mine (size 8 boot remember) so you have an idea; I've the heel loop at the center setting ("1") and the gas pedal at the center setting.
-From lowest part of highback padding to edge of gas pedal: 10 3/16 inches (25.88 cm)

 

Wow thanks!

And thanks to everyone that replied, including union guy/girl for the last comments.

 

Here's what I should have said, instead of directing you to the size chart:

I have no idea what the sizing is like on Nitro Crown boots. If they are average fit (sole width and upper volume), I would suggest going with the medium size.

Thanks for the support.
