Feet going numb on bike?

Now that I’m logging more miles on the trainer, I’ve noticed that my feet go numb after 15-20 minutes or so. What are the causes of this? Is it the pedal/shoe combo? or my saddle? or could it be a geometry issue?

I am currently using my running shoes and the old straps on the pedals (can’t afford clips yet). I’ve tried running the straps really loose, but it doesn’t seem to help a whole lot.

There was a thread on this forum somewhere discussing this very topic, but without a search function, I’ll be darned if I can find it.

Thanks.

Funny that it happens when you use your running shoes!

For me this ended when I bought new shoes (they both were cycling shoes).

When I first bought my cycling shoes nobody told me I had to go 1 number higher than what I normally would buy. So that did the trick for me.

I have a pair of Sidi T2´s and love them! Can ride and ride and my feet are well ventilated and the numb issue disapeared.

Re-tie your laces with the bow at the end of your foot (close to your toes). This will take the pressure off of the veins and nerves on top of your feet that are being pressured from the position on the bike. Should help.

I think you don't have a stiff enough sole. Your foot might be "curling" around the pedal cause your foot to go numb. I had this same problem when I was riding with tennis shoes a while ago. I switched to stiffer sole and the problem went away. Ideally it would be nice to switch to a cycling shoe, but look in your closet and see if you have a shoe with a stiffer sole you can use for your bike.

If you keep your running shoes, try Yankz. Maybe the foot gets too constricted based on how you tie your shoe.

Typically though this happens with cycling shoes and pedals. My Sidi's are too narrow, the soles have softened out, and the Speedplay 'lollipops' provide such a small platform that it causes numbness in the middle of my foot. (I love my bomb-proof, two-sided clip-in pedals, though). So when you get clipless, think about getting the largest platform (ie, look at the size of the platform against which your foot will push on a Speedplay vs. Look), properly fitting cycle shoes, and a stiff sole (don't waste the $ on carbon, though).

It also aggravates the problem when you ride on a trainer. When you ride on the road, you are constantly shifting your weight and stuff, so your feet/butt/hands will tend to go numb more easily on trainers and rollers than on the road.

But I would definitely look into getting some look pedals and some cycling specific shoes. Good luck.

I had this problem riding on my spin bike with toe straps in sneakers as well. Went away completely when I started riding on the trainer in my cycling shoes. I'm wonder if there's a home remedy of stiffening up the sole of your sneaker somehow...

To tri or not to tri - that's not a question at all!

you just gotta go get pedals! eat ramen for a while if you have to!? im not the type to get into fancy extravagent stuff, but clipless is so important. the stiff sole and upstroke (toe clips dont really compare) will change your riding so much!
a common mistake with whatever shoe you wear, is over tightening. you dont need to lock hammer down on the laces.
p.s. i also recommend LOOK
