emily it's wednesday and I hope you see this before your ride tonight! If you don't already DO lubricate your cleats pre-ride! It will allow them to unclip much more easily. If you ride a lot and walk in them, you may have some dirt, schmegma in them that is making it more difficult to unclip! That's why I lube mine once a month or so... even just unclipping and setting down on the road can attract dirt to them... hope your ride goes well and unclipping is easier than you thought it would be!!!

I was riding Frogs and had to switch to zero's as well, because I would get sloppy when tired and ended up with a pretty bad ITBL strain... I really pay attn to my form now, but the zero's have also made a difference as I cannot get as sloppy with them!
