For the matter at hand, rig is perfectly fine. Valve never intended for Spy's model to have thick ankles thus, never made a rig to accomadate any such thing.

blame valve on that, the rigging on spy sucks major ass.

It looks good when spy is tposing but, first image shows how ugly it bends when animated.

This is surprisingly well done considering you had to model over Spy's default model. Well done.

maybe we swill soon get a naked spy

I think this is the first pair of Spy shorts i've ever seen on TF2 Workshop.

Why wasn't this for sniper?

for some reason spies thighs are disturbing me

That trench coat outfit gave me a chuckle. I think his ankles look a little thick, but I'm not sure if that could actually be improved due to these (presumably) having to hide the Spy's pants. But these would be great to get since Spy has barely any pants cosmetics to begin with, and these are completely different. :) also love that it has a plain style without the suit stripes. great work
