These are the BEST socks for little people on hardwood and tile floors!! Highly recommend them. I purchased them for a very active 4 & 2 y.o. who love to run and chase all through the house and were constantly slipping and sliding on the floors. These socks have solved that problem. They can now run around like crazy and are no longer slipping, sliding and falling! I purchased the Toddler size socks and they run true to size. They fit both kids who's shoe sizes are 9 and 10. I will definitely be purchasing more of these socks as their feet grow.
