INOV8Inov-8 Men's Bare-XF 210 V3 - Minimal Barefoot Cross Training Shoes - Black/Gum - 10.5

I have been spoiled by toolbox with from zero shoes and Altras.Is the toebox comparable with those shoes does anyone know? It is a major factor for me

Heel pads inside? Those give me blisters

I noticed in the preview for the beige/black color way there's actually two different colored shoes shown. Which color would you receive?

Are the sizes listed on amazon in us or uk measurements?
