The 303’s are £200 but I’ve seen them cheaper than that so are pricey. However as someone else put I’m banking on them lasting me a couple of years at least.
They are waterproof, and suitable for riding in sub zero temps.
They have an inner neoprene I think lining that closes nicely round the foot, and then they do up with boas which are ace and a clip that pulls the top part round to protect water ingress from the top.
They are so good and comfortable that I am not wearing my normal shoes anymore,.
Easy to walk in, I was concerned about rub round the calf area but nothing. They are just superb, and even went bike hiking today coz we got lost and and stepped into s boggy water by accident and my feet were completely dry! Best money I think Ive spent on bike stuff!
