Which step tracker?

Hi all.

I've been using the Samsung Health step tracker for a while, but it the synching randomly stops after a few weeks - sometimes I can get it to reconnect and record steps again, but it takes quite a lot of faffing about.

I don't like having things on my wrists, and have never worn a watch.

I'd like to have something that clips to my shoe and then syncs the steps up to the MFP app - does such a thing exist?

I've searched all over, but all I can find is fitbit and clones that strap to your wrist.
