WR, I gave Catrin some PI shoe covers last year for her to try that, last I heard, didn't end up working with her cycling shoes. I can't remember now if I told her to just pass them onto someone else or return them to me when we next saw one another, but if she still has them and doesn't want them, you are welcome to them instead. For what little winter cycling I do, I prefer toe covers and chemical warmers. You might like them. If memory serves, they have some rubber around the cleat opening and zip in the back.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
