What does grouser mean?
A grouser is a projection or tooth fitted to the underside of footwear so that it grips loose, wet, or slippery ground. Deep grousers on hiking, climbing, or work boots can make a substantial difference in stability, especially on mud, gravel, or ice. The word also has a technical engineering use for a block, rail, or similar fitting positioned beneath a track or structure to limit spreading or movement. In literary use, a grouser is a person who habitually grouses or complains, though this sense is much less common. Grouser should not be confused with grouse, the bird, or crampon, the complete frame of metal spikes attached to footwear. As a verb, grouse means to complain or grumble, and it is especially associated with British informal usage, though it is also understood in American English.
A grooved or toothed projection on the underside of footwear, used to grip a surface.
"The deep grousers on his boots gave him firm footing on the ice."
Common in descriptions of outdoor, work, or climbing footwear; it normally denotes an individual projection rather than a whole crampon.
A block, rail, or similar fitting placed beneath or between railway rails or structural members to prevent spreading or movement.
"Engineers replaced the worn grousers beneath the track."
A specialized engineering and railway term.
A person who habitually grouses or complains.
"The old grouser found fault with every plan the committee approved."
Uncommon and literary in modern English.
The plural grousers is standard, especially for the individual gripping projections on a shoe.
"Mud packed into the grousers of his boots."
Think of grousers as the hidden teeth of a boot: the small projections that turn footwear into a climbing tool.

Where does grouser come from?
The mechanical noun grouser appears to have developed from the verb grouse in the sense of grinding or making a grinding sound, with the name referring to a fitting that grips or braces against another surface. The verb grouse itself comes from an Old French word associated with grumbling or complaint and is cognate with Old French grousser, “to grumble.” Modern senses have developed in both the complaint-related and mechanical branches of the word.
How grouser is actually used
In footwear, grouser usually means a tooth or ridge on the sole rather than the entire spiked attachment. The sense for a complaining person is uncommon and literary, and should not be confused with the mechanical senses.
