Michael Phelps his keeping his family with him as he heads off to Rio de Janeiro for the summer Olympics.
While the 31-year-old swimmer’s baby boy is too young to stand by his dad in Rio, little Boomer is set to follow in his footsteps -- with a little help from custom Under Armour shoes!
Former Olympian and current NBC swimming analyst Rowdy Gaines tweeted the adorable evidence of Phelps' sentimental sneaks: a pair of his shoes with Boomer's footprint inked into one of the insoles.
"Loving @MichaelPhelps shoes w son Boomer's foot imprint on one of them…so dang cute," he posted to Twitter on Sunday.
The decorated Olympian has received tons of support from his new family. In June, Phelps' fiancée Nicole Johnson brought their infant son to cheer him on
as he competed in the Olympic Trials.
"#teamdaddy all day err day!! We LOVE you @M_phelps00 and we're cheering super loud for you!!" she wrote, along with an adorable shot of Boomer sporting a "team daddy" onesie.
"Mom and I are excited to go watch dad tonight!!" read another post, from Boomer's Instagram account.
Phelps and his model fiancée welcomed their son in May, just in time for their little one to watch his dad compete in his last Olympics.
