It's great to get larger sizes. I've not worn this in cold weather yet, so don't know how warm they are. They are cosy round the ankle and i like being able to adjust them.. The fur inside is much shorter. Would have been great to have the same inside as well as ankle as I have very cold feet. I tried these with a medium sock and think they would be too tight in width and length with a heavier weight sock. I bought a uk11. I don't usually buy Remonte and thought they would be wider. They will be useful from autumn through spring.
