What is this on my foot?!

I just looked down and saw this. If doesn’t hurt. It kinda looks like a blister or a burn but I feel like I’d remember it happening and it’d have some soreness to it. It seriously just popped up. I really want to pop it like a blister but idk. What do you think this is?

Update. It was a water blister. Popped it and now it’s gone. Yay! Lol
