I want to order the boots but there is no size that's indicated. Is this a boot that fits one size fits all?

There are sizes for the Technica Moon boot. They are a bit confusing but Technica combines sizes. If you look at the drop box, the one that says "Select Options," above the "Add to Cart" button you'll notice that the different colors available drop down. To the right of those colors you will see two numbers (i.e. 39/40) and those indicate your sizing. These are not your typical US sizes so you will need to click on the "View Size Chart" option, below the drop menu" to determine you size in US sizing. Happy shopping and if you ever need immediate help feel free to chat online with one of our Gear Heads. They are extremely helpful.
