Swimmers have been known for unique footwear in recent years, most notably Ryan Lochte, and Michael Phelps has added a new entry.

Check out these shoes from the U.S swim team’s Atlanta training camp, snapped by NBC Olympics analyst Rowdy Gaines.

The shoes noticeably have not only what appears to be the footprint of a baby (Boomer Phelps turns 3 months old on the day of the Opening Ceremony on Friday), but also logos of Under Armour, a Baltimore brand Phelps has long partnered with, and his own MP logo from his new line of swimsuits.

Phelps’ cheering base in Rio is expected to include both Boomer and fiancée Nicole Johnson.
