Really incredible boot! With daily use as a paramedic, I have found my health. Very hard sole that initially scared me, but as soon as I wore it for the first 10 hours, I realized that it is preferable and I did not get tired at all, waterproof as it gets and durable triple stitched with rubber sole. After 12 months, it is still like new. For those of you who are thinking of spending serious money on boots and if you are among them and prefer Haix, choose Lowa, it is miles ahead 5/5. Try them, don't buy them online
