These boots are adorable. I'm a 21 year old female and I usually wear a size 6. I actually wear a 6 1/2 in my Vasque hiking boots. But when I got this pair of 6's in I couldn't even walk in them. Haha. I loved them, but they were enormous! I would recommend going a size down...an ENTIRE size. I'm not exaggerating. I sent them back for a size 5 in kids. Here's a tip: look at the UK sizes in your other shoes. Then get the size of these boots that corresponds. My 6 1/2 Vasque's are a size 4 in the UK, and these Sorel Boots are a size 6 but in the UK, a size 5. I should have been more observant! I hope this helps!

...but I thought they were size 4 infant (as it had infant written on the size description), upon receiving them, they are too large for my infant son, who would have been 12 months when wearing them - they would fit a 12 year old. But great boots, wish they made them in size 4 infant sizes...
