It's rare to see a new enchantment added to Minecraft, but the Wild Update delivers an exception from Mojang. A new enchantment called Swift Sneak is now available to players and is very different from the style of enchantments seen before in the game.

While most enchantments deal with damage protection, Swift Sneak is similar to Depth Strider in the sense that it increases the movement speed of the player under certain special conditions. Here's where the enchantment book spawns, and how it can be best used by players in Minecraft.
Swift Sneak is a new enchantment that can only be found in a loot chest. In that sense, it's similar to Mending, only, for now, it seems that villagers also do not sell this enchantment in their inventory. This means Swift Sneak is a fairly rare enchantment.

This enchantment book can only be applied to leg armor, so leggings of any tier will do. Simply place the book and the leggings on the anvil interface to apply the enchantment on the armor piece.
Swift Sneak comes in three tiers, from Swift Sneak I to Swift Sneak III. The fourth and fifth tiers are only available through commands. Each tier increases the player's walking speed while crouching by 15%. The first tier starts at a 45% faster walking speed, while the third tier provides a 75% speed boost while crouched.
