my feet are going numb when riding. Why is that and how do I correct it? I do have clips.

Just some of my thoughts.
1. experiment with slip placement on your shoe
2. loosen your straps across the top of your feet
3. concentrate on pushing down and pulling up in the pedal stroke.

My feet use to go numb (around 20mi marker), and during my mid-ride, I loosen the two Velcro straps and found it to cure my issue. YMMV.
P.S. I also found it changing cadences every few miles and a lot of toe wigging to be helpful (probably not proper cycling etiquette).

Cleat position can have a larger impact than you would think. I would take an allen key with on a ride and try a few different positions to see if it helps. They also sell a decent amount of shims for under your insoles that cn help alot with comfort and fit of the shoes, personally I have three different shims under each insole and my shoes fit like a glove and my feet remain as comfortable as they can when pedaling all day.

This used to happen to me during my distance running. I would try to loosen up your shoes a bit and see if that helps.

the guy at the bike shop said to go with the clip pedals that have more space on them (look like a regular peddal but they can be clipped in). He said it gives your foot more support.

Does that sound right to you all?

It depends because all feet are different, some people cant stand looks, other ones loves them

IMO the 2 main reasons feet go numb is because of lack of support and because actually you feet swell or get Swollen after a few minutes and then since cycling shoes arent slippers the feet go numb big time and people doesn't realize it at all.

Assuming you have the cleats in the right place and you don't have any other pain in the sides of your foot, but numbness, just move them 2 or 4 mm back and take the insoles out of the shoe or replace them with something super thin just to test, even thin card board or 1 mm balsa wood works is just a test. If the pain goes away and you are ok after 1 hour, just put the cleats back in the old position and continue riding. If the pain did not come back is clear that your feet needed more room, so probably getting 1 extra size shoe will do the trick just fine. In my case had to go from a 43 to a 44.5, started having the same problem after like 25 years, so I assume is only because im getting old.

Good luck.

Good luck.

you're pedaling too much with your toes

I was having same issue & now loosen my straps about 10 miles in & have very small to intermittent issues with it now. Experiment from ride to ride. Make adjustment & ride for another 10 to 15 miles before judging it. Also come out of the saddle from time to time if you're not.
