if i had to tell younger fathers one piece of unsolicited advice: buy arch support for your shoes. Plantar fasciitis seems to creep up on a lot of dudes after they have kids. It's also the worst.
I love to carry my kid but sprinting around while carrying the extra load did a number on the feet. You can largely prevent it just by spending $50 on a proper insole.
My kid is my favorite thing in my life. So tiring, so rewarding. And after a year of wincing walking barefoot, I can finally run again. Don't lose running time with your kid, buy insoles.
Happy fathers day.
New flex: i use arch support btw
As a father who is suffering from plantar fascitis (brought on by running), I would rather fix the problem by strengthening my arches than mask it by buying inner soles.
I find compression helps at least as much as support for my plantar fasciitis.
I'd recommend something like the links below for going barefoot:

I think both companies make a compression band without a cushion, so it won't interference with your insole. (I use 3" elastic sewn in a loop, costs about $1 for a pair.)
Good anti-fatigue mats for anywhere you stand a lot are great as well.
