I have similar problems with new hiking boots Asolo Eldo Mid LTH GV, soles burn terribly and hurt after 2 hours of walking. To solve it I changed socks, loosened laces, changed insoles, etc..... but nothing helps.
They advertise them as agile light boot, breathable and waterproof. But I have such problems with them as not for a long time

....
Previously I had very good experiences with Asolo boots...
Is there any solution at all? Thanks.
