Need help!

So my husband and I plan on announcing the pregnancy on social media after the next appointment at 8 weeks and 3 days which is in two weeks. My husband and I met at a bowling alley for the first time 2 and half years ago. We love bowling. We go every chance we get. So I planned on getting baby bowling shoes, and lining up our shoes and babies shoes. On the back of his I'll put dad, on the back of mine I'll put mom, and on the back of the babie I'll put " coming soon" " Feb 2017" and the top caption would say " one more is joining our team!" I was wondering if anyone knew where I could buy the bowling shoes?
Do NOT say Craiglist. I refuse to go on that website. Thank you :)
