sneakers

The word 'sneakers' is a transparent compound from the verb 'sneak,' which itself descends from Middle English and has Proto-Germanic roots related to the act of creeping or moving stealthily. The '-ers' suffix, a common agentive ending in English, attaches to form a noun for objects. The term was coined in the late 19th century because the quiet rubber soles of these shoes allowed the wearer to move without making the noise typical of hard leather soles, thus enabling one to 'sneak around.' This literal, functional description based on a property of the object (quietness) became the standard name for this category of casual athletic footwear.
