Pronunciation: [hˈɒbne͡ɪlz] (IPA) 
Hobnails are studs that are hammered into the soles of shoes for added durability and traction. The spelling of this word can be a bit tricky, as it includes the consonant cluster "bn." In IPA phonetic transcription, hobnails would be written as /hɒbneɪlz/. The "h" is pronounced as in "hat," the "o" as in "hot," the "b" as in "bat," the "n" as in "not," the "ai" as in "bait," the "l" as in "love," and the "z" as in "buzz."
Hobnails are small, sturdy, nail-like metal protrusions that are specifically designed for reinforcement or protection of footwear, particularly boots. These robust nails have a characteristic pattern of circular heads or ridges along their shaft, which enhances their grip and prevents slipping on different types of surfaces. Hobnails are typically made of durable metals like iron, steel, or brass, which ensures their longevity and resistance to wear.
Originally, hobnails were primarily used in military boots or work boots to provide additional traction and durability in challenging terrain or harsh environments. However, they have also been employed in various recreational activities such as hiking or mountaineering, where stable footing is crucial.
The act of affixing hobnails to footwear involves hammering the nails through the soles of the boots, allowing the circular heads to emerge from the lower surface. This creates an effective grip on various surfaces, including mud, snow, or slippery terrain. Hobnails are often embedded in a specific pattern to distribute weight evenly and maximize their gripping abilities.
Due to advancements in footwear technologies, hobnails have become less commonly used in modern times, as many modern boots are designed with molded rubber soles or specialized treads that provide improved traction. However, hobnail boots continue to be favored and utilized in certain niche areas like historical reenactments or by those seeking a more traditional and heritage-inspired footwear option.
The word "hobnails" is derived from the combination of two words: "hob" and "nail".
"Hob" comes from the Old English word "hobbe", which referred to a peg or a large pin. It had various uses, such as a block of wood on which a pot could rest or a peg inserted into the ground to secure something in place. Over time, "hob" came to be specifically associated with the metal piece attached to the sole of a boot or shoe.
The term "nail" comes from the Old English word "nægl", which referred to a thin, pointed piece of metal used to fasten or secure objects together.
When combined, "hobnails" literally means "nails used in hobs".
