Each champion begins the game with a particular base movement speed, ranging from 300 (base champion statistics., and 11 others) to 330 ( and ) units per second. For a list of all champions' base movement speed, see
- (Base Movement Speed + Flat Movement Bonuses) × (1 + Percentage Movement Bonuses) × Slow Ratio
Diminishing returns are then applied to the result.
Flat bonuses are applied first, then percent bonuses and slows, then diminishing returns. Most bonuses and slows are given as percentages. The exceptions are:
- The passive aura on .
Remember that 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 under, 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 below 220, it gets multiplied by 50% and added to 110.
- Example: if the calculated raw speed is 180 before soft caps kick in, it is increased to 180 × 0.5 + 110 = 200.
Slowing effects follow particular rules when stacking:
- If a champion is affected by multiple slows, the strongest one will be fully applied, while the others are applied sequentially with 65% reduced effectiveness down to 35% of its original strength.
- Slow effects derived from items' passives do NOT stack, even when coming from different champions. Only the strongest item slow is applied at any moment. The exception to this is the active effect of , and , which stacks with other slowing items normally because they are considered champion abilities for slow stacking purposes.
- Attacking a champion with the buff when the target is already affected by that slow will reapply the debuff, resetting its duration. It will NOT increase the slow amount. The same holds true for the Exhaust summoner spell.
A champion with a raw movement speed of 400 is affected by a 2 second long 40% slow and a 5 second long 20% slow at the same time.
- For the first two seconds, he will 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 will have 400 × 0.558 = 223.2 raw movement speed.
- For the following three seconds, the effective slow will be 20% and so he will have 400 × 0.8 = 320 movement speed.
- After that, he will return to his normal speed of 400.
Increasing flat movement speed
Purchasing boots from the store grants a champion a flat increase in movement speed. The effect given by boots is called Enhanced Movement and is unique, which means that if a champion has multiple pairs of boots, they will only receive the highest Enhanced Movement bonus. The bonus from boots is quite big compared to their cost and is essential for all champions.
- Enhanced Movement 1 increases the base movement speed of a champion by 50.
- Enhanced Movement 2 increases the base movement speed of a champion by 70.
- Enhanced Movement 3 increases the base movement speed of a champion by 90.
- Enhanced Movement 5 increases the base movement speed of a champion by 130.
Enhanced Movement gives 20 movement speed per rank plus a flat 30 movement speed. As such, basic boots have a higher speed-to-cost ratio than upgraded boots.
In addition, some champions have abilities that increase their movement speed by a flat amount.
This is a complete list of boots, ordered by cost:
- Unique passive: Enhanced movement 1 (50). 350 gold :
- Unique passive: Enhanced movement 2 (70). Unique passive: Reduces the damage taken from non-turret autoattacks by 10%. +25 armor. 850 gold :

- Unique passive: Enhanced movement 2 (70). +20 magic penetration. 1100 gold :
