About two years I used it and my heel was worn out, but there was no soaking of water by cracking etc. It is large because it is premised on wearing thick socks. Adjust by increasing the insoles if loose. The cold weather ability is much warmer than ordinary boots, but it is no use holding too much expectation.
Although it is the first anti-cold oil resistant shoe, I feel it is very heavy because there is a lining of a bore, because the making is large. Sneakers etc. I am wearing it in 26 cm, I chose women's socks, double wearing socks though, but I chose a bigger 27 cm, but there is a width than the boots I wore so far, my feet will swim in my shoes. Another insole insole is likely to need a thick insole. I am satisfied so far for the cold weather.
