Help with sizing for AnatomX African Ranger
So I'm trying to figure out what size would be best and having a hard time deciding.
I only have one pair of barefoot shoe that I wear and that is the Lems Chillum, which is a size 9.5US, and they fit perfectly on me (best pair of shoes I ever had tbh). But, the actual measured length of my feet from heel to big toe is 10.75inch (27.305cm) and 4.25inch (10.795cm) wide.
According to Jim Green's sizing chart, I would fit into a 10 1/2 US.
I'm just a bit wary of ordering a full size up from 9.5 US (Lems). I know different manufacturers have different sizing but a full size up is making me a bit nervous.
Also, the width, the Lems insole seems a bit narrow compared to my feet (I have flat feet) but tbh I never noticed or found an issue with it while wearing those shoes. So I'm a bit confused here.
Should I stick with the AnatomX version of these boots or look into the normal barefoot version or even just the normal African Ranger version of this boot ?
