You probably remember that weird bug, when you shooting and pressing movement keys at the same time, players legs goes crazy: http://youtu.be/xque-f6lK2w
Well, i tried to fix it in this mod, also with some other features:

-press aim button to show crosshair. It's will be hidden otherwise.
-hold left ALT key to walk.

[VC] Walk 1.1 for aiming mod is a special version for upcoming Manual Aiming mod with the ability to run and aim/shoot at the same time. So, basically, legs movement fix just disabled.
