Multiple pictures posted in support of this question confirm that the outside of the boots were slick - the hair-on side could not have been outside. (simple logic dictates that the hair should go on the inside to keep the foot warm - hair on the outside isn't going to trap any heat. Hair on the outside might work for fashion, but the images indicate that the Mongolian fashion was for bright dye.)
There are also an intimidating number of pinterest links that my have further details. I don't use pinterest, and pinterest is fairly hostile to anyone who doesn't have an account, so I'll leave that research for someone who is pinterest friendly

According to The Field Museum's Genghis Khan online exhibit...
Manβs Boots
Leather, 19th-20th century, National Museum of Mongolia
These centuries-old leather boots are like those worn by warriors in Genghis Khanβs empire and nomadic Mongolians today.
For battle, these felt-lined leather boots were often covered with armor plates as well. The turned-up toes signify respect for the land by minimizing the mark they left on the ground.
While the boots in the exhibit are not 13th century, the exhibit states they are of a similar style. The leather would likely have come from cattle or yak. So yes, "cowhide".
(As a side note, Discover Mongolia offers a different explaination for the upturned toes: "it's also true that boots are so thick and rigid that if they were flat, they would be almost impossible to walk in.")
Here's a Mongolian tanner describing the process of making traditional leather.
