I bought these because my 12 year old son (yes he has big feet) wears size 10 men's tennis shoes so I bought a size 10. They're a little big, but there's room to grow. He constantly wore his socks outside for everything. It drove me crazy! NOW he wears his Puma indoors and out! I love these shoes and thank goodness they save me money on socks! Hooray! I WILL BUY AGAIN IN HEART!
