Most riders obsess over shorts and jerseys, but the humble sock is one of the most important touchpoints you’ve got. Assos clearly knows it, because the new GTO Sock isn’t an accessory. It’s a full rebuild of what an endurance sock can feel like.

They used Sens ST, a soft, cool, almost weightless fabric that wraps the foot without any hint of bulk. The ventilation is dialed. The compression is even. And the silicone grip built into the arch keeps the sock planted when the ride gets long and the terrain gets rough.

It’s a quiet piece of equipment, but a serious one. Elegant, comfortable, and designed for riders who understand that the details matter just as much as the headline gear.
