If these were any wider they would not fit l/XL bindings! Damn good boot for the price. I had burton ION's prior to these and they were not wide enough. My toes have considerable overhang now but I should have bought a wider board. I can't blame Salomon for that!
These bindings are the SHIT! I bought them six years and Rome has replaced straps and hardware free of charge. Try getting that from UNION. I had to buy another pair because Forum, Burton and union just were not cutting it.
