Will L/XL fit on standard boards(waist)? and will my K2 11 size boots fit in L/XL?
They might but it all depends on how wide your waist actually is. The top half of the binder should be fine, but I dunno about the base. I ride a Rome Machine W with a waist of 258 and I have about 2cm clearance on the toe and heel(from base to edge of the board). If your board is something like a 250, you might be ok. But these binders do run a tad smaller than my Contacts and Forces, so you might be able to get away with them. And yes your sizee 11's will fit in the L/XL. Just tweak them down to fit your boot proper. I have a size 12 boot and ride last years Contacts and the binder isnt maxed to the biggest setting, so you will be fine
