My daughter was in hysterics when these arrived for her. They really are fluffy and she loves fluffy things. She insisted on wearing them around the house. They did come up tight but they are so squishy that it doesn't really matter and they will squish down all the fluff over time so I would still buy maybe 1/2 size bigger or 1 size bigger if you want to wear thicker socks. They are chunky and come up to a bit below the knee on my daughter.
These are brilliant, warm and very comfortable. My son loves them and the colour and style is really nice and very simple to tighten the lace. Water resistant so I don’t need to worry about him having wet feet. Grip on souls are deep and seem very grippy. Need to wait for test on snow!
