Functional but a bit uncomfortable
I wanted to buy a pair of Hunter boots for a long time, allsole.com was doing promotional discount so I finally got myself a pair of boots and fleece socks, prices are more reasonable with discount, otherwise, it's too pricey for a pair of rain boots from my opinion.
I think they are perfect for rainy days and I'm sure that they will do a good job in cold weather if you wear it with their fleece socks, I tried on the fleece socks with the boots but it looks bulky on me.
The downside is it's a bit uncomfortable for me to wear but only on my right leg as my inner ankle got scratch by the shaft all the times and it actually has a lot of room inside, so I don't know why. And, it's a tough job for me to take them off ;p
I'm a size 39 and I bought the UK6, fits perfect.
I like the look of them, the size and the colour but the right boot is a little snug on my leg. That's great for stopping rain entering from the top but makes it a bit tricky putting them on because they push up my trouser leg. The left leg is better; still not loose. Just be aware if you have larger calfs.
