You can't beat a good foot.
Agree, going up stairs would be rather difficult and down them probably hurt a lotOnly when going downhill.
I'd go for a bionic pair and can run like the 6 million dollar man.Seriously, they are revolting
They are my least favourite part of the body
Yet they are also essential
I just find them disgusting
I have the opposite to a foot fetishism
I have a foot revulsion
Toes are pretty much useless too other than for letting us know we've walked too close to the edge of the bed.

Too unwieldy.But you don't use it as a rule
Useless? I can pick things up with my toes....
Well without the big toe we couldn't walk. I'm sure the whole foot is quite important though.
I use metres. It's easier now.Seriously, they are revolting

But what about baby feet? I'm with you on adult feet, most of the time, being the ugliest part of an adult human.Seriously, they are revolting

Claws are useful for climbing up trees, but they were in the way when our arboreal ancestors moved into the trees, grew larger, and began moving about on smaller branches, grasping and swinging rather than digging in. Flatter claws became were selected for, and eventually became nails.Something I've never thought about so after reading your post i did a little research...
Toenails are vestigial, and at one time in our ancestral tree they were necessary for defense, digging, climbing, and were used as tools
Though they are assumed to now be used to protect the toes so maybe not completely vestigial.
They used to have more of a purpose. Maybe someday humans won't have them anymore.What would you like to have there instead, if you could freely redesign the human body?
My only wondering with our feet is, why do we have toenails? they don't really seem to serve any purpose. They are not strong enough to protect against anything, they are not particularly practical down there, and we can't use them to climb trees, or scratch any places that you can't with your fingers.
Why evolution hasn't gotten rid of them yet I don't know, I have no clue what their purpose is
What selective pressure is there to eliminate them?They used to have more of a purpose. Maybe someday humans won't have them anymore.
Claws are old, really old and ubiquitous. Every group within amniota seems to have them or had them with very few ever losing them. Snakes lost them together with the legs and cetaceans lost them. All other marine mammals still have them including manatees. All birds have them on their hind legs and some still have them on their wings.Claws are useful for climbing up trees, but they were in the way when our arboreal ancestors moved into the trees, grew larger, and began moving about on smaller branches, grasping and swinging rather than digging in.

Nails can be useful, and they're metabolically inexpensive. There's no selective advantage to be gained by eliminating them, so I expect they'll persist.
