During hot summer days, can you wear just liners with trail running shoes, or is it necessary to use regular socks?
I'm going to be using a pair of Soloman Crossmax Xr trail runners this summer to walk around town, on trails and off the beaten path, and I really like the lightweight-ness and breathability of my Fox River Mills liner socks. Why even use regular socks in hot weather if the liners do the job of regular socks (protecting from blisters, wicking sweat, etc.) for a fraction of the weight?
I understand that in some cases (like if you were running and wanted some extra cushion or it was winter and you needed to keep your feet warm) regular socks would be better. But what if you're just doing light activity (mainly walking) in trail runners and the weather is hot?
