These are for Lowa boots so get the right ones for the boots. My old ones are two years old and the aglets are peeling off which makes rethreading them after cleaning a bit difficult. These now live in my backpack's first aid pouch ready for when they're needed. (Next clean I imagine!)
With quality and durability every time, it's no wonder Lowa boots are the UK's go-to footwear for utmost comfort and performance!
