If you want to have good air permeability, choose the new GORE-TEX XCR high-permeability waterproof membrane, which is 50% more breathable than ordinary GORE-TEX. In addition, the choice of low temperature resistant socks is very important. Choose Smartwool or bridgedale (/kloc-about 0/00 to more than 200 pairs) genuine wool socks, and make sure there is no problem.
For shoes, I recommend you try TrekSta. Although it is a Korean brand, the quality and objective evaluation of international and domestic donkey friends are good, which is more suitable for Asian feet. MAJESTYM in the middle and Kobra-530-GTX-Ml below are both Gore-Texcr.
There is no need to be superstitious about V-soles. The top shoes of famous brands such as SCARPA, LOWA, GARMONT and ASOLO are not necessarily V-shaped soles, but they are often the soles of their patented technologies. In a word, the shoes with low top 1000 and high top 1300 are actually not fooled by the manufacturers, and the V-bottom is only one of the manufacturers' choices.
