How the fuck do you kite someone with movespeed buff?

Deal as much damage to them as you can while moving in between auto resets before they reach you so that by the time they do get to you, they are already half or near dead.

It also helps to not go alone.

Slows, cc, dashes (over walls especially), summoner spells.

Mostly just slows though. Any champion that doesn’t inherently have mobility spells or slow resistance is susceptible to being hard cucked by slows.

Depends on your champion.

You don't. Your best bet is when you can start forcing teamfights, and then those Udyr and DPS garen's struggle to be useful. As long as the game state remains where they can run around fighting 1v1s and 2v2s, you probably dont stand a chance as an ADC or some squishy champion they can get on. You basically have to force an ARAM. Once that happens, though, they basically become cannon fodder.

Generally you have 3 options:

1. You lock them down with CC. You can't run if you can't move, so them out-running you is impossible. You can also slow them to reduce their speed instead of outright removing it. Either way, it stops them from running. Most non-trivial slows will be enough to make you faster than them. This is useless against Olaf and Yi for obvious reasons. --
2. Run at a similar speed for longer. You don't necessarily need to out-run Garen, you just need to stay away/stay close enough from/to him (depending on whether you're trying to get away or get closer) until his speed boost wears off. Udyr you can't really do that against, since his speed buff effectively lasts as long as his mana pool does, so refer to option 1 or 3. --
3. You don't. You might just be too slow or they much just be too fast. If they're running away take advantage of the situation to do something productive. Your only real option to fight them is to force them to come to you (or to run away from you, depending on what you want). If it's the former you want, you could go for drake or some other objective to force them to respond, where getting away is losing the fight. If it's the latter...get fed? I guess? There's unfortunately not much you can do there yourself that isn't just "Just be fed 4head" since there's very little other way to be enough of a threat. You can have your team help peel for you, though, which gives a similar result to kiting them.

by being ranged

Maybe Kindred is just not your champ

You know.... i was expecting this to be a Yi rant since all the others can be slowed.... i was disappointed.
