I would compare the soles to a single thickness dainite. They wear similarly to single leather with just a bit more rigidity. I love the low profile look from the top and side perspective. Traditional 'double dainite' can sometimes command a casual presence while these, I feel, have more versatility.
The leather reminds me of regular EG calf. Where Utah/Delepre would have that buttery feel, these have a bit more heft to them. I find that by comparison, GG's calf tend to be a bit thinner where as this feels like there is some thickness to it, without conpromising comfort.
Was that helpful? Just my perspective.
