First thoughts - sizing feels true. I wear a UK Size 12 in Doc Martens and these feel basically the same. Top of the boot dug slightly into the back of my leg initially, then stopped.
Some slight, very slight, heel slippage (even with a thick-ish sock), but that's the same as my Docs and I choose that over going down to an 11, which I think would be too tight.
In New Balance runners I wear a UK 11.5 and that seems pretty much perfect, so if these came in half sizes, that's where I'd be. But in this situation, I think going up made most sense.
