Movement speed is a champion statistic that represents the rate at which a champion travels across a map. One movement speed point translates to one game distance unit traveled per second (as a frame of reference, diameter is 100 units). For example, a champion with 300 movement speed will be able to walk three in one second.

Each champion begins the game with a base amount of movement speed, ranging from 325 (e.g. and ) to 355 ( and ). For a list of all champions' base movement speed, see base champion statistics.

This base movement speed can be increased by flat bonuses and percentage bonuses and reduced by slows. These effects can come from items, champion abilities, summoner spells, masteries, runes and environmental buffs.

## Calculations

A champion's movement speed is given by the following formula:

(Base Movement Speed + Flat Movement Bonuses) × (1 + Additional Percentage Movement Bonuses) × (1 + First Multiplicative Percentage Movement Bonus) × .... ×  (1 + Last Multiplicative Percentage Movement Bonus) × (1 - The Highest Slow Ratio × Slow Resist Ratio)

Flat bonuses are applied first, then additive percent increases, then multiplicative percent bonuses, then the strongest slow affecting the target, then any caps that apply. Note that slows do not stack. Because bonuses and slows are applied to each other, a champion affected by a 20% bonus and a 20% slow still has a net reduced movement speed (e.g. 300 × 1.2 × 0.8 = 288).

### Movement speed caps

When the raw movement speed is greater than 415, there are two soft caps applied:

• The raw speed between 415 and 490 gets multiplied by 80%.
• The raw speed over 490 gets multiplied by 50%.

The two ranges have their reductions applied at the same time before being added back together.

As an example, if the calculated raw speed is 600 before soft caps kick in, it is reduced to (600 − 490) × 0.5 + (490 − 415) × 0.8 + 415 = 530, which means an 11.7% reduction of the original movement speed.

These are the simplified formulas:

• If the raw speed is 415 or lower, no cap is applied.
• If the raw speed is between 415 and 490, final speed is soft capped to RawMS × 0.8 + 83.
• If the raw speed is above 490, final speed is soft capped to RawMS × 0.5 + 230.

When the raw movement speed is less than 220 another soft cap is used:

• If the raw speed is below 220, it gets multiplied by 50% and added to 110.
Example 1: If the calculated raw speed is 180 before soft caps kick in, it is increased to 180 × 0.5 + 110 = 200.
Example 2: If the calculated raw speed is 0 before soft caps kick in, it is increased to 0 × 0.5 + 110 = 110.

Only slow with the highest value affecting particular champion is taken into calculations. All additional slows are ignored until higher-valued slows wear off. When highest valued slow decays, another affecting slow is calculated into.

The only exception to this is when the slow exceeds 100%, in which case the target ends up with 0 movement speed.[1]

### Slow Resist

Slow Resist is a statistic that reduces the effectiveness of slows by a percentage. It may currently only be gained by the mastery, , , and . Slow Resist stacks multiplicatively.

A champion with , a movement speed of 400 and who is affected by a 40% slow will have a movement speed of 400 × (1 − (0.4 × 0.75)) = 280, which is equal to a 30% slow without slow resist.

## Increasing flat movement speed

The bonus given by these items or champion abilities are flat increases to the champion's base movement speed. These flat bonuses will increase the effectiveness of percentage bonuses.

Purchasing boots from the store grants a champion a flat increase in movement speed. Champions cannot buy more than one set of boots. The bonus from boots is quite big compared to their cost and is essential for all champions.

## Increasing percentage movement speed

The bonus movement speed given by these items or champion abilities are based on a percentage of the bonus compared to your total flat movement speed (before all sources of percentage movement speed bonuses are factored in). Percentage movement speed will stack additionally with other sources of percentage movement speed, unless the bonus movement speed is the few exceptions that stack multiplicity.

All percentage bonus listed below stacks additionally with one another.

## Multiplicative speed boosts

Most speed boosts stack additively, but a select few stack multiplicatively with other speed boosts. These do not stack additionally with other percentage movement speed bonus, but rather are multiplied after all other percentage movement speed have been calculated. Movement speed obtained thanks to the formula is still affected by movement speed caps (see above).

All other damage instead briefly slows Quinn and Valor. Upon dealing damage or activating , the effects of end.

### Summoner spells

• grants you and target ally 30% bonus movement speed for 1 second.

## Old slow stacking

Since patch 5.13 only slow with the highest value is affecting. All additional slows are ignored.

Prior to patch 5.13 slow stacked:

Slowing effects followed particular rules when stacking:

• If a champion was affected by multiple slows, the strongest one would be fully applied, while the others were applied sequentially with 65% reduced effectiveness down to 35% of its original strength.
• Slow effects derived from items with the same name or named item effect did NOT stack, even when coming from different champions. Only the strongest item slow was applied at any moment. The exception to this was the active effect of , , and , which stacked with other slowing items normally, because they were considered champion abilities for slow stacking purposes.
• Attacking a champion with the buff when the target was already affected by that slow would reapply the debuff, resetting its duration. It would NOT increase the slow amount. The same holded true for the summoner spell.

#### Example

A champion with a raw movement speed of 400 was affected by a 2 second long 40% slow and a 5 second long 20% slow at the same time.

• For the first two seconds, they would have (1 − 0.4) × (1 − 0.2 × 0.35) = 0.6 × 0.93 = 55.8% of his original movement speed (a 44.2% effective slow). So he would have 400 × 0.558 = 223.2 raw movement speed.
• For the following three seconds, the effective slow would be 20% and so he would have 400 × 0.8 = 320 movement speed.
• After that, he would return to his normal speed of 400.
