This demo is for the Asics Mens GT-2150. For other shoes, look for the shoefitr button on the product pages of all the sites listed here.
Shoefitr uses 3D scanning technology to scan insides of shoes. Each scan provides measurements pertinent to fitting a shoe to a foot.
When you are shopping online and find a shoe you want to buy, you tell Shoefitr the size and model of the shoe you currently wear.
Shoefitr then compares the measurements of the shoe you are currently wearing to the one you want to buy and recommends the correct size.
Shoefitr also provides two fitting tools showing how the selected shoe will fit so you can see if it will accommodate your personal preferences.
