!rule 1 That is not normal you should tighten you cleats down in the position you do not want them to move from. Tighten them firmly. Then tighten some more. Done by hand you’re basically not going to over-tighten them. There’s some info in the wiki (here) and the sidebar about cleat positioning and tightening, including some great YouTube videos by bike shops. You could also go into your local bike shop and ask for help, you’ll learn a lot and make some new friends and probably find some things you might upgrade to down the line! The shoes and cleats used with Peloton are standard fare for road bikes as well, so the advice you’ll find anywhere online regarding Look Delta cleats and shoes will be fully applicable to your question. Good luck!
