Ladies, i'm brand new to this site and have only been spinning for 8 months. I've had spin/cycling shoes almost the entire time and as of late have had a lot trouble clipping in and out of the pedals. (they're spin bikes, so it's not the same pedal every time.) They're spd cleats...do I need to lubricate them? I got stuck tonight, had to take my foot out and a man in my class had to pry my shoe off the pedal. What gives??? I've only recently been having issues. Does it matter how i've adjusted my cleats? I'm sure they're tightened well. Can anyone help??? I don't know that cleats could be worn out this quickly, but like I said, i'm relatively new to this. Thanks so much for your help
