I bought the winter boot version of these and they're excellent - good grip, good fit, good materials.  Was looking forward to these for summer us (I know people who ride with them and they stand up to abuse very well) 

BUT they're slightly smaller volume than the winter version. It's marginal and I wore them sitting at my desk for some hours before concluding that they were too snug to be comfortable and I'd had them a while (injury) and had initially thought they'd be ok so waited too long to return

The sizing is accurate - I think I measure my foot as 285 and these have the right amount of extra space at the end, they're just slightly too narrow across the widest point of my foot (I think I need nearly 110) and the combination of width and my high instep means they don't have the volume to compensate for the very slightly narrow width
