While the size marked on the inside of these skates says "10," the shoe itself is just 7-inches from heel to toe. Early roller skates with a boot attached to the wooden rollers were originally called "shoe skates" when they first became popular at the turn of the century. But in the 1960's plastics revolutionized roller skating with lighter weight skates and modern wheels that made them more durable as well as faster.
With this in mind, it would seem these skates are vintage 1950's. Each weighs nearly 2-1/2 pounds. The wheels are marked "Arrow Skates" and appear well worn. There are no shoe liners on the inside and only one lace. All of the wheels turn smoothly and they measure 2-inches in diameter. Great gift to get someone started with a new hobby before you buy an expensive brand new pair.
