Speed boots give a player an extra six movement points per turn, plus a 1/3 chance of an additional six movement points. This boosts the normal movement rate from 12 to 18 (150% normal speed, or 3 moves every 2 turns), with a 1/3 chance per turn of movement rate being 24 (200% normal speed, or 2 full moves per turn). On average, the player will thus get 20 movement points per turn (167% normal speed, or 5 moves every 3 turns). Speed boots have no effect on your steed's movemetn speed while riding.
Speed boots are the only source of extrinsic speed that doesn't time out, making them popular choice for an ascension kit. Very fast speed is a huge basic advantage for any character, moreso than even intrinsic fast speed - with more actions per turn, you can deal more damage with weapons and spells, more easily flee from combat or employ hit and run tactics) and slip through gaps in hostile monsters before being surrounded. Blessed fixed +2 or +3 speed boots are a common early wish, though gray or silver dragon scale mail is arguably a preferable option, depending on your circumstances.
Speed boots are of little use to humanoid pets that can wear them - most such pets can pick up and use the wand or potion, and some spellcasting pets can make themselves fast easily. Extrinsic speed is typically not necessary for dedicated riders, who prefer other types of boots - wearing jumping boots allow your steed to jump and can cover more distance than speed boots, while water walking boots can save your life if you're dismounted over water. Bear in mind that no steed is immortal, and you should be prepared to continue on foot if necessary in case you lose them to an accident or unfortunate circumstance.
Speed boots are a valuable item in turncount speedrunning, due to their ability to give the player multiple actions without advancing the turn counter. An air elemental polyself is even faster than this, though you cannot wear boots in this form.

In SLASH'EM, Whisperfeet is an artifact pair of speed boots that acts as a luckstone and confers stealth when worn - they are the guaranteed first sacrifice gift for Tourists. The black market shopkeeper, One-Eyed Sam, is always generated wearing an enchanted pair of speed boots; a pair of speed boots also appears in The Spider Caves.
In GruntHack, armor can have the speed property, including non-speed boots, providing more sources of extrinsic speed.
