I would try replacing you bike shoe cleats. They are probably really worn. It is a pretty cheap fix.

Use your foot to tap one shoe so that the crank arms are parallel to the ground before you run with your bike. The shoes then won't contact the ground (which is what causes the shoes to come off).

And for God's sake, man, check your spelling.

I'd also just practice a bit and be mindful about what is going on. For instance there are a few reasons why cranks might rotate when you are running alongside pushing your bike. You can check that bit very quickly. If the cranks are rotating then when the heel of a bike shoe hits the ground it can be spun anti-clockwise very quickly and then jam when it comes back around and hits the ground. If that is what is happening then you need to figure out why the cranks spin, which might be something simply like a sticky freewheel. But that is a specific example, I'd run through it a few times and try and get a picture of exactly what is happening.

The comments regarding the sticky freehub and tapping the cranks level are the solutions for your problem. Also, the longer your cranks are and the closer your cleats are to the toe the less margin you have for error.

My shoes nail the ground using my roadbike. TT bike has 165 cranks and that 1cm makes all the difference.

Ha ha! Sorry about that! That's because I was typing it on the treadmill and didn't check it! He he! Thanks for the advice, I'll try that.

This has been happening to me recently as well. I have new cleats, but I do a flying dismount so one pedal is necessarily in the down position after I get off. Also I wear size 12 shoes with 172.5 cranks, that probably doesn't help. I will have to practice setting the shoes parallel after dismounting (if it can be done quickly) and see if that helps.

Depending on the pedals you use, you might be able to adjust them so you require more force to get in and out of them. That's what I did... solved the problem.

I assume you are dismounting on the left in the usual fashion. As your right foot is about to touch down, very slightly “kick” (like pulling through while pedaling) the left pedal back to set the cranks parallel to the ground.
