Bought these for the coming wet months since I use my bike to get to work and my usual go to hitops arent waterproof (learned that the soggy way). I'm usually between a 5 and a 6 in shoes/boots and opted for the 6 at first, thinking that might be enough to counter the smaller than expected sizing, but alas, i was also cursed with my fathers feet, and ended up in a 7. They're really comfortable, and can confirm so far, very waterproof. I got caught out on my way home today but my feet/the area of my jeans tucked into the boots was still bone dry. Very happy. I will say - despite looking grippy, I do slide about on (wet) smooth surfaces/tiles/manhole covers, its not the end of world, I just have to pick the more beaten paths I guess! Also, the returns process for the first pair was easy & the folks in customer service were lovely as always. Thanks!
