On the quality of the soles, I can not see any flaws. (She had now been 8 weeks) comfort I find very pleasant. (Soft and feathered) Even the smell of sweat is not an issue and it appears as the soles are well ventilated. Only, the sole thickness is very thick, but you can probably make between thin => less cushioning and thick => more comfort technically a few compromises. I would recommend for men's shoes.
