I bought these for the sole purpose of power lifting. however, these are not true barefoot shoes. there is a slight arch which isn't mentioned in the product description (though amazon does mention this when I did a little further investigation) which means they're not completely flat soled. as a result, the shoes aren't suited for what I bought then for, as the arch would cause inward movement of the ankles when squatting, which may eventually result in injury because of the resulting instability. this is why when you see people squatting in regular sneakers, you'll see their feet begin to buckle inward from the weight. sadly, I'll be returning these.
