can you get enough movement speed off runes to not buy boots?

yeah maybe at full build you can sell your boots and get another item lol but nobody would want to not get boots. speed is the best thing in league of legends. ive never seen a rengar play without boots, its like his core item.

the only champion who i sometimes saw without boots is riven with 40%-cdr build because she basically has infinite jumps.

Well, Rengar players tend to forego boots for the sake of that "OMFG I DIED IN UNDER ONE SECOND" nuke burst. Some champions CAN get by perfectly fine without boots, but they do tend to be core for the majority of champs.

Not in high Elo. I have seen multiple player run CDR boots before even finishing their jungle item.

They also get a ms boost from ulti and yomus, which is the only time a rengar player really matters anyway.

Boots counts as Base 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.
