i have an anecdote (love the quote in your sig) ... the garneau tt gloves look fast, fit tight, and claim at least to be aero.

Ah those are my favorite gloves for any ride. So comfy its like a second skin with some palm protection.

Whatever fits tight, has no wrinkles, and has no velcro straps or anything.

FWIW local fast TT'er Dean Phillips says he tests faster with the Castelli aero gloves than with no gloves http://fitwerx.com/...p-winning-cervelo-s5

Not sure if he's tried others but he seems pretty meticulous about his selections.

If you can deal with the weird look: http://www.castelli-cycling.com/...D-GLOVE/p/451402815P

Funny that the ST concensus these days is that most shoe covers aren't aero -- specifically that only the rubberized shoe covers help -- yet these "aero" gloves Castelli describes as neither wind nor waterproof.

Skin is slow.... the weaved sock, plastic and fake leather of your typical shoe is a much faster base.

Latex? Only sort of joking ;-)

I think it's the same reason skinsuits aren't wind or waterproof...just too damn hot.

Team Sky uses basically the thinnest fabric they can get for max breathability....it does have some issues though (sartorial and otherwise).

Yeah, I was thinking that as well as depending on your hand position, isn't it possible that the large 4-finger opening would "scoop" air and slow you down?

From my talks with Jim at ERO Sports, I would hazard to guess that this style glove might work very well with certain hand positions and not so well with others. Yes I know, insightful analysis. OK, really just guessing. But I know ERO can measure real aero differences when riders simply tilt their wrists differently in the extensions - I would be surprised if these gloves were not fairly "grip dependent."

FWIW - I tested with Jim at ERO a couple weeks back and the Castelli gloves were neutral (using ski bends). Also tested with and with out booties. The SMART booties tested better than without booties.

I've often wondered if shoe covers work better on shoes with velcro straps that hug the body of the shoe than they do on shoes with dials and buckles.

At some point, I would love to get a pair of custom Bont Zero Plus shoes (I am unfortunately in the middle of their available stock sizes) and just be done with it... my guess is those shoes are about as aero as you are gonna get, outside something like the Chrono.

If they are skin-tight, then lycra is fine. If they have gaps that catch air, then no.
