Just echoing what some of the other ladies have said:

Mashing down on the pedals will put more pressure on the nerves of the ball and arches of your feet. I can tell whenever I get sloppy with my circular pedaling this will happen and I will get a little numbness. Focusing on smooth pedaling always will release some of that pressure (I used to unclip and shake my foot which can help too).


Getting shoes that are too small is probably one of the more straightforward things to cause numbness. I bought 2 pairs of shoes that both wound up being too small by just basing the purchace off my normal sneaker size and how they "fit" ok in the store based on how I would buy sneakers. Apparently I like my shoes snug in shoes but this doesn't work with bikes.

Sidis run very small. I have the $230 pair variety also, and I went with a shoe size 2 larger than my normal size (from Eruo 36/7 to 39) and now I have no major numbness problems. The toe box somedays still feels small with thick socks so for long rides I still take the extra thin socks with me.

Other problems would be an improper bike fit which puts you at a bad geometry and you are putting pressure on a nerve "further up" which you then feel in your feet.

My instinct tells me your shoes might be too small considering just how large I had to go to get a proper fit and foot problems I've had in the past related to too small shoes.

Before you go buying new shoes, try wearing the thinnest possible socks you own and see if that makes your problems any better. If it does you can always Ebay those old pair and spring for the bigger size. Its worth it!.
