Yes. Shoes. All for rear of cart. You'll buy a set of shoes (4 in total). Two will have an L and two will have a T. Grab an L and a T for each side. The L goes towards the front of the cart and the T goes towards the rear. Repeat for the other side.
You'll be able to tell the top and bottom of the shoe. The L and T is what trips people up. Ask me how I know.
