Finally, I was able to test ride.
I started to ride when temperature was around 25 with a little back wind 5-10mph. I have warm Performance pants on, regular cycling socks and wool socks. I have my regular shimano shoes with mesh top. The shoe covers are light and look cool. The first time I noticed some cool in my toes was after 40 minutes ride. But it was not bad at all. I started really feel them only after 2 hrs, but it was a headwind too. At the end of my ride the temperature rose to 30-33 degrees, but when I got back home, my toes were pink and cold.
I believe the shoe covers performed well, however, I am thinking to cover mesh parts of my shoes with duct tape for extra protection next time.

Here is my ride.
