Black zero drop barefoot shoes - Size EU38 (7US?)

Black minimalist barefoot shoes. Bought from Amazon. Zero drop, wide toe box. Size EU38 which is a size 7 US according to Amazon. My shoe size is a US7 and they fit me so I’d say they are right. I measured the sole if that can help with sizing (see picture) Note: THERE IS NO INSOLES INCLUDED In great condition. They’ve just been in the washer so they are clean and smell free.
