Grape colored size M2W4 crocs.  If the color or size is wrong, you can trade them in at Ten Toes Shoes.  Ten Toes Shoes is a great new children's shoe shop in San Carlos.  Very helpful and friendly staff.  Here are a couple of reviews I found on yelp.

"An upscale children's shoe store: what a classy little addition to downtown San Carlos! Privately own, the small space has a well thought out balance between styles, brands and prices. The few toys in the mix are distinctive. Really helpful service to pick out just the right first shoes for my baby but also for my 3 year old with a nice little sock/stocking selection as well."

"Ten Toes is a family shoe store. It is so nice to have someone take the time to make sure my children have the perfect fit !!!! It so nice to not have to drag my kid's into the mall for shoes. Now we can just run into Ten Toes! So Easy and fast."
