A well-built trekking sock that manages warmth, breathability and fit effectively.
Lorpen says:
Medium-thick sock with padding over the entire foot, ventilated zone in the instep and a very good ankle fit. Constructed with recycled PRIMALOFT and RWS merino wool to provide a great balance between insulation and breathability. With a Comfort Plus cuff that provides greater comfort and prevents excessive tightening of the calf.
Our Verdict
The Lorpen Pro Trek Midweight Crew weighs 85g (Medium pair) and combines merino wool with recycled Primaloft for cushioning and thermal control. Padding is placed where impact is highest, while mesh zones across the instep keep airflow steady. I found the flat toe seam prevents rubbing, and the cuff sits securely without digging into the calf. The fit adapts closely to the foot, avoiding creases that can lead to blisters, and the stretch content ensures they stay in place through long wear. Durability feels in line with Lorpen’s reputation for technical socks that handle repeated use without thinning prematurely. Lorpen, a Spanish brand with a strong focus on performance knitting and sustainable fibres, has built a consistent following for high-quality trekking socks, and this model reflects that attention to detail. A solid option for those needing dependable midweight comfort in variable conditions.
