A fastener system for clothing and other personal items is disclosed. The fastener system uses a combination of materials to form elements that can be adapted to different fastening applications. A first component of the system includes two members. The first member has an aperture for accommodating a T-shaped attachment member and a button. The second member has a T-shaped attachment member that fits through the aperture and rotates sideways to prevent passing backward through the aperture. The second member also has a strap for securing the attachment member against the aperture by attaching the strap to the button. A second component of the system includes a button with an enlarged head and base, and a flexible washer that fits over the head of the button. Fabric of an article to be secured may be laid over the head of the button and secured around the head of the button using the washer.

An article of footwear includes a front end, a rear end, a sole structure, an upper attached to the sole structure, and a strap system engaged with the upper. The upper defines a forefoot region, a midfoot region, and a heel region of the article of footwear, and the upper and the sole structure together define an interior cavity. The strap system comprises a strap configured to tighten portions of the upper within the heel region in response to the user's toe movement within the interior cavity.
