Blis-Sox® Gel-Lined Socks - Heel Blister Protection (One Pair)

Blis-Sox® Gel-Lined Socks put a cushioned gel patch exactly where heel blisters start. Worn under your normal socks, they cut friction and absorb impact around the heel and Achilles, so new shoes stop rubbing before the damage is done.

We stock them for one reason above all: breaking in new climbing shoes. The seamless open-toe design slides under your usual socks without adding bulk, so you get extra heel comfort without changing how the shoe fits or performs. They work just as well for running, hiking, walking, gym sessions, cycling or any long day on your feet.

Why you'll love it

• Gel-lined heel protection – a built-in gel patch reduces friction and rubbing to stop blisters forming
• Softer stretch-knit fabric – breathable, soft against the skin and durable enough for daily wear
• Seamless open-toe design – no bulk under your normal socks, works with any footwear
• Achilles comfort – absorbs impact around the heel and tendon during high-activity movement
• Kind to climbing shoe fit – extra heel comfort without affecting performance or how the shoe fits

Good to know

• One pair per pack
• Two size ranges: UK 3-8 / EU 36-41 (Black) and UK 8-14 / EU 41-49 (Grey)
• How to use: wear Blis-Sox® underneath your normal socks so the gel lining sits directly on the heel

Who it's for

Anyone who suffers heel blisters – runners, hikers, gym-goers and especially climbers easing into new, tighter shoes. A handy small gift for a climber too.
