It is an old model or a product that we can no longer order at the manufacturer.
The Drifter I Evo GV are walking shoes for men, designed by the brand Asolo, to accompany you on all paths and trails. These Asolo shoes feature a suede upper, which is both breathable and water-resistant. Your feet will stay dry even if rain makes an appearance. This waterproofing is further enhanced by the Gore-Tex® lining of these walking shoes. Additionally, you will enjoy the excellent comfort of the Drifter I Evo GV thanks to the dual-density EVA midsole. The Vibram® outsole, on the other hand, ensures a high level of grip and good toe protection wherever you go. Finally, this same sole features self-cleaning lugs that will provide you with high performance on various types of terrain.
I already knew these were good boots, just hard to get hold of. I'm a professional mountain walking guide, this is my third pair, definitely my non technical boot of choice.
