Help understanding what I should be feeling(or not) during first week of transition

TLDR at bottom because I do love to just keep typing.

Hey there, I just started my transition to barefoot shoes a week or so ago and I just want to know if other people felt this during their transition or not. I've been wearing my barefoot shoes to work at this point, and though I work an active job I am probably only on my feet a total of 4 hours out of 8 a day due to many opportunities for breaks. I also am a person who is barefoot as much as possible at home.

First, the bottoms of my feet are a tad sore by the end of the day. I was recently on a vacation where I was walking like 15+ miles a day and my feet would ache by the time I got 5 miles in(this was all in normal New Balance shoes). Anyway, it was all the parts of my foot on the very bottom that were aching, like the ones that make contact with the ground. With my current usage of my barefoot shoes (3 to 7 hours a day) should my feet hurt at the bottom. They don't ache like crazy like the did on the trip, I just want to know if it is normal for that part of your foot to be in pain as you adjust to no cushioning.

Also, I don't feel anything in my calves when I am wearing barefoot shoes, but I do feel it in my shins. As soon as I feel any pain in my shins I stop wearing my barefoot shoes asap because I know shins are something you don't want to mess with.

I just don't want to make a mistake with transition. I know you should take it slow, but I can't tell if my foot pains are just part of the transition and I should keep wearing them or if I need to be more cautious. I am finding a surprising lack of transition information other than which shoes to pick. Any info is appreciated and I would love some non-youtube foot workout info if anyone has some good ones. Thanks!

TLDR: Is it normal for the bottoms of your feet(the parts that make contact with the ground) to feel a tad during your first week of transition? What about pain in shins?
