I had DH change my pedals on the road bike for the first time this week, to wear my PI winter shoes. Last year, I used them only on my hybrid, which has spd pedals. Though I was not cold using my road shoes, toe covers, booties, and wool socks, it was a pain putting on all of that gear. Though I won't take my road bike out once the roads are full of salt and slush, I figured I might want to use the boots for my first few rides in March. I am debating whether to leave them on for when the bike goes on the trainer.
