I have the Apollo Hybrids also from Arket for about 6 weeks and so far pleased with them. Have worn them loads in the rain and they are waterproof and very warm. I wear them without socks sometimes as they are fully fleece lined.
The downsides for me are they are completely synthetic, great if you don't want to wear animal by products, but for the same price you could get good quality sheepskin lined boots which are more breathable. Also they come up a size small, I'm a small UK5 and got the 39 and they are not big - hence wearing fine without socks.
