Ehecksher - the Shimano W101 are definitely on the small and narrow side you may need to go up at least one size. I had those before my current boots in a 38 which is my normal shoe size (about a 5) and they were so small they made my feet even colder and almost crippled me , I gave them to a friend who has dinky size 4 feet and she likes them.

Try before you buy, if you can't make sure you wear them around the house in thick socks for a good while to see if they are comfortable or not - don't put cleats on them till you are sure.
