Brand new Vision hopper wading boots (eu 44, Us11, uk 10).
These are brilliant boots, and if they were my size, I'd grab them. I've hammered my Hoppers across Assynt & Uist, wandered the Don all season in them, stomped up to hill lochs elsewhere, and the boots still look almost perfect - I'm very very impressed. And super comfy too, and easy to get on and off.
I'm a UK 9 shoe size - I have these Hopper boots in the EU43/US 10 size, and they are a great fit, even with thick socks and neoprene stocking foot waders. MOST companies advise you to buy wading shoes one size bigger than your show size - I've seen one online reference for these boots suggesting just buy your normal size, and that's how my experience goes with them - in fact, if anything, they are a fraction too big!
So if you are a UK 10 - buy these!
