Abstract: A length-adjustable shoe, of which a length between a front end and a rear end thereof is adjustable, includes an outsole, an upper, a stretch fabric, and a control device. The upper includes a body portion and a heel portion which are mutually separated, wherein the body portion is directly attached on the outsole, and the stretch fabric connects a bottom edge of the heel portion and the outsole. The control device connects the body portion and the heel portion, wherein the control device moves the heel portion relative to the body portion as a whole in an axial direction from the front end to the rear end, which changes the length of the shoe.

Abstract: A jersey is disclosed, which includes a first portion made of a first material, and a second portion bonded to the first portion. The first portion comprises a main fabric, which is adapted to cover at least a chest and a stomach of the user. The second portion is adapted to cover at least a part of a back of the user, and includes a peripheral sub-portion and a center sub-portion. The peripheral sub-portion is provided along a periphery of the second portion bonded to the first portion, and the center sub-portion is surrounded by the peripheral sub-portion. The peripheral sub-portion is made of a second material, which is more flexible and more breathable than the first material. Whereby, the jersey could better fit the body shape of the user.
