It is hard to purchase shoes online as there is just no standard sizing across different brands or even within the same brand. There is a tool called the visa-meter (used in some kids shoe stores) which is adjustable and is used to measure the length inside any shoe. It would be so handy if the length of the shoe would be available under the product description. This would save sooo much back and forth- which I'm sure would completely change the game for online shoe shopping in terms of increasing efficiency and overall customer satisfaction. I am also sure that word would definitely spread- because I have not heard of anywhere else that does that
