SHOE TALK
Rock plate
Specific to trail-running shoes, rock plates are hard plastic inserts situated between the midsole and outsole of the shoe to prevent sharp objects from injuring the foot. They can run the full length of the shoe, only under the forefoot or some variation thereof.
Drop
The change in height from the heel of the shoe to the toe of the shoe. Some shoes have zero drop (like Altra) and some shoes have very high drops (like Salomon).
Stack height
The combined height of the outsole and midsole; the distance of the footbed from the ground.
Last
The shape of the foot mold used for designing and making shoes.
