A featherweight liner that keeps feet cooler and drier, especially when paired with a thicker sock for big-mile days.Injinji says:Injinjis Liner socks are designed to be worn as the first line of defense against excess moisture and blisters, keeping feet dry and comfortable. The five-toe design forms to the contour of your foot, allowing for natural, restriction-free movement. With each toe separated, all skin-on-skin contact between the toes is eliminated, helping to prevent blisters. Wear the Liner socks as a baselayer under an outer sock for extra cushion, or wear them alone for lightweight protection during everyday adventures.Our VerdictThe Liner Mini-Crew Coolmax from Injinji is one of those small details that can make a real difference on the trail. They’re ultra-thin and low bulk at just 2g (Medium), but the five-toe construction offers excellent blister prevention by keeping each toe separated and dry. Ive always liked toe socks for reducing hotspots, and these work exceptionally well as a base layer under a cushioned outer sock. The Coolmax yarn helps move moisture away efficiently, even in warm conditions, and the mini-crew cut sits neatly under most boots and mids.Theyre fine for short, easy-going days, though I wouldnt count on them for durability if worn solo over rough terrain. Fit is snug but forgiving, and the 200-needle knit makes them feel smoother and more refined than earlier Injinji models Ive used.- Reviewed by Ultralight Outdoor GearFeaturesBlister PreventionMoisture ManagementTotal Foot Utilization200 Needle-CountUltra-Thin BaselayerCoolmax EcomadeSpecificationsMedium pair weighs: 24gLarge pair weighs: 27gMedium Fits: UK 7-9 / EU 40.5-44Large Fits: UK 10-12 / EU 44.5-47Height: CrewMaterial & ConstructionFiber Content: 63% Nylon 33% COOLMAX EcoMade 4% LycraCushion: Ultra Thin CushioningHelp & advice:The Benefits of Merino Wool
