Yes, I thought it was well established that aero covers coming as high as the rules allow are way more aero than any shoes.

Is it important to have the aero shoe, or is a cover, like the anemoi, something that would be more beneficial? It's obviously not going to be foot shaped, but it seems like the option at the minute is to cram your foot until an unrealistically shaped shoe, or suffer an aero penalty.

Specifically for Allan - would you trust an aero tri shoe for Norseman, for example? When the weather can be like last year? My last few xtris I've used a shoe with some weather protection, and cleaned it up with the anemoi cover.

Hey Allan,

Yeah, for the person who said go for the narrowest shoe, there is something to that. There are two main issues to consider with drag on a shoe - the frontal area against which there is high pressure pushing you back, and the amount of area on the trailing side exposed to low pressure caused by flow separation and turbulence. Reducing frontal area is easy. But a foot is the size and shape it is, so you can only go so far and then it becomes painful. Reducing the low pressure behind the shoe is much more difficult, but it has the benefit of being able to reduce drag without squishing the crap out of your foot. Reducing the drag of a shoe is not really about minimizing or hiding closure devices like BOA's.

I took the approach of starting with a lot of Computational Fluid Dynamics simulations of conventional shoes and understanding where and why flow separation occurs and what surface areas are then exposed to the resulting volumes of low pressure, and to do this at several different foot angles (i.e. how much the toe is pointing down). I then went on to experiment with A LOT of different shapes to delay that flow separation and expose as little trailing edge surface to low pressure as possible. I also made the choice NOT to make our shoe super narrow, even though that would reduce the drag even more. The goal is to be both aerodynamic AND comfortable for most people.

I know you have been waiting on us at VeloVetta as we have been delayed, literally, for years and I apologize. Of course it is very frustrating and I am embarrassed each time I have to tell someone we have hit yet another snag. BUT - here is an update. All of the uppers, carbon soles, plastic and metal components, etc for our first batch of 1,500 pairs of shoes is complete and at the factory for final assembly. Lasting and assembly will happen this coming week and the week after. Each batch that is completed each day moves on to have the wires installed. Then they will all get boxed up and shipped to my warehouses and then they will be available.
