OK, the Falke SK Energising compression ski socks are pricey but they do come with more features than the average ski sock, namely a blend of natural (merino wool) and synthetic (elastane, polypropylene and polyamide) materials which offer gradual ‘class two’ compression to your hard working calf muscles whilst you’re skiing.
What this means in plain English is improved blood flow for your muscles, better oxygenation and thus less fatigue.
In addition the merino helps keep your feet warm and doesn’t attract odours, whilst the synthetics provide better wicking and thus help prevent sweaty feet, whilst the overall feel of the socks is light, warm and comfortable.
But do they work? Well when I used them I have to say I didn’t feel any tiredness in my calves at all although I had several days skiing under my belt so they were used to the activity.
On balance I’d say the SK Energising socks do help to reduce fatigue, and they’re also really nice to wear, so if you’re happy to spend £40 on your ski socks you’ll probably see some benefit from it.
