Northwave get my vote. I recommend going up a size on your regular size. Wear thicker socks in them. Don’t do them up too tight.
Wear an ankle gaiter over them to stop water getting in thru the hole where you got / ankle is.
That said… Go to a real bike shop and get fitted. Don’t trust STW on this or risk an online purchase. Either take your own thick socks or use those that the shop has. Take your time and use the sales assistant. Don’t be embarassed about this in a very British way. Ask for different sizes, and different makes. It’s your money and they’re getting paid to do this. This is a really personal thing. You’re gonna spend a chunk of cash on this. Get it right!
Overshoes are rubbish. It took me three sets and roughly £75 to realise this. Proper winter boots are one of your best buys if you ride throughout the year.
