Crocs Kids' Mammoth EVO Clog - Waterproof & Comfortable Lightweight Slip-On Shoes for Boys & Girls - Perfect for Playtime, Beach, and Outdoor Adventures

Many folks recommended buying a size larger for the Crocs with the lining. I found with my daughter who is a size 2, this not to be true. I ordered a size J3. For the size "J3" - I could not find out what that meant exactly from the manufacturing, but I ordered them since that was the only size 3 available I could find at the time I bought these (end of October) and I figured others were ordering for Christmas or to get warmer shoes for the cold weather approaching - so selection seemed to be limited. I wish online the retailers would just say "kids" sizes - not "toddler, kids, young adults, adults" - as a parent who has purchased shoes for two kids, I know the transitional size is11-12 from toddlers/ little kid to 12-13 for the older kids.However that said, while the croc is larger, it is not so big that she can't wear them. The liner is warm and the foot does not slip in the shoe. They will fit her a long time and I like that value. I bought them to wear to and from swimming lessons in the winter because trying to put socks on wrinkled feet is a challenge and her regular crocs are not going to keep her feet warm walking from the building to the car. The crocs are high enough off the ground the slushy snow won't get in them and the heel is high enough when she is wearing yoga or sweat pants to cover the back of the foot.
