Can someone who has *actually* used these for barefoot-like running suggest sizing to me? One questioner mentioned getting half a size smaller. For

I got my regular size (8.5) and they're starting to feel way too loose as I'm starting to do more actual running ... but I think what may be happening is that the uppers are just wearing out -- I've worn them almost daily since March (it's the end of October as I write this, and I walk probably 5 miles a day, so that's probably getting close to 1000 miles on these).

Do they have individual toe slots inside?

No. The toe box is open. The outer style of the shoe looks like there might be toe slots but it is open inside.

I run on asphalt would these be ok?

I run on rocks and because they’re thin, it hurts. Asphalt is flat so it should be ok. But I use them on rocks so I react faster and not twist or roll my ankles. I no longer slip. I no longer roll my ankles. It’s because They help me feel out the ground beneath me that running shoes do not. What would usually take me 17 or 15 minutes to run downhill now takes me 12 minutes per mile and loose rocks are a very unstable and hard surface to run on.
