Slow Ashe

So I've been playing League solidly for about a month now. I main Ashe, she fits my style of play and all, plus hey, I've always loved her classic skin since before I even knew what this League of Legends fuss was all about.

The one problem with Ashe I've increasingly begun to notice as I try more difficult matches is her movement speed. There is no way to kite. I end up hugging towers or praying my support doesn't blow a play when our team makes a shift. And even with my slows, I barely have any chance to make a run for it when my team is on the retreat.

I know I'm still pretty new to this game, but ever since the Boots of Swiftness nerf, I have noticed that I pretty much have no chance of escaping whatsoever when things collapse. I have started selecting both Flash and Ghost as my spells now because there is simply no other way for me to escape a bad position--and even then I will get caught by a Lucian or sometimes even a Jhin. Even when I use my R to stop, say, a charging Blitzcrank, he still is able to make ground on me after the stun is over. Boots hardly seem to increase my odds of survival.

I know this is a game and logic isn't always consistent with reality, but my archer who is all about 'moving swiftly' seems to be one of the slowest champs in the game that I'm so far aware of. I checked out her stats on the wiki and for an ADC, there's not much lower than her. Even Kog'Maw has the same movement speed.

Is there some secret I don't know about Ashe's movement? I feel sooooo slow on top of being squishy.
