My toes & the balls of my feet go numb, but it doesn't just happen during cycling. I first noticed it a decade ago when I took up sea kayaking.

Anytime the area of my sit bones is compressed, I pinch something. That's what makes my toes go numb. I happens if I sit wrong on a hard chair. Using a women's saddle makes it worse. It's an odd thing, and I glad I figured it out before I started cycling. Otherwise I would have wasted tons of time trying out different shoe/pedal/seat combinations.

My 'cure' is getting up off the saddle every 15-20 minutes, and taking a break off the bike every hour or so.

I haven't talked to any other cyclists with a similar wiring problem, but I cannot believe I'm that unique!
