These cozy crib shoes are the perfect accessory for your little one. Not only do they feature ultra cozy material, but they also have a beautifully embroidered Catholic symbol. This symbol is a great way to teach your children and also help them to be comfortable sharing their faith from a young age. The symbol on these shoes is the Chi Rho. This symbol has been in existence since very early Christianity. It was commonly used to designate Christian places. The Chi Rho is formed by two Greek letters: the chi and the rho. These two letters are the first and last letters of the name of Christ in Greek.
