LD Mountain Centre Says:
Like all Smartwool PHD Ski Socks this lightweight version is technically designed to provides comfort, breathability and a performance fit. These thinner, lighter weight ski socks will work really well for those looking for a close performance fit from their ski boots without losing comfort around the foot.
