Baby Boots

Long story short, I'm trying to get pregnant. My dad is a horse trainer. When we do get pregnant, I would like to tell him by saying I have a question about his training. I'll ask "how is (his favorite horses name) with kids?" And hold out a pair of baby-sized cowboy boots.
But I need help!
I, for the life of me, can't find any cute cowboy boots in newborn sizes that are gender neutral! Walmart has a really cute pair, but they're pretty girly. Does anyone have a suggestion, or can post a picture of some for sale somewhere? I would like to keep it under $20... Thank you
