Swift Sneak is a rare treasure enchantment for leggings that significantly reduces movement speed penalties while sneaking and crawling. This exclusive enchantment can only be obtained from ancient city loot chests, making it one of Minecraft's most coveted mobility enhancements.

Swift Sneak comes in three standard levels, increasing crouch speed by 15% per level. At maximum Swift Sneak III, players move at 75% of normal walking speed while sneaking - transforming from sluggish 30% to nimble stealth movement. Higher levels through commands can reach 100% walking speed.

This enchantment proves invaluable for stealth gameplay, ancient city exploration, and avoiding sculk sensors. Players can even sprint while sneaking at higher levels on Bedrock Edition. The enchantment also enhances crawling speed, making it essential for navigating tight spaces and maintaining mobility during careful exploration.
