Know this is a bit niche, but I love these slippers, where I live it's super cold & these are amazing. Cotswold Outdoors have a huge warehouse clearance + upto 40% off Flash Sale + Free Delivery on Orders for the BH Weekend, so well worth a browse on the site, will pop links in 1st post.
Luxuriously warm yet reliably hardy, the Women’s Nuptse Tent Mule III is the slip-on your feet would choose for downtime in extreme cold. Featuring Primoloft ThermoBall insulation for lightweight warmth, this is a great shoe for relaxing at base camp before or after ascents to the top. Despite its low profile and cosy appeal, the slip-on also boasts tough construction too, its durable ripstop upper resisting water and abrasion – and it’s engineered from recycled post-consumer plastic waste for environmental peace of mind, too. Underfoot, the nylon mesh base features grippy plastic lugs for traction on slick surfaces, while inside there’s a sock liner for an extra dose of comfort.
Upper: 100% recycled ripstop PET
Sole: Nylon mesh with rubber traction lugs
Sockliner: Die-cut EVA
Insulation: Primaloft ThermoBall
Please note that these tend to fit a little smaller than the initial size would suggest.
