This boots were comfortable from the first time I put them on, no breaking in time at all. I love the leather lining for comfort and breathability, no sweaty, stinky feet as I even get with GorTex linings. I have bunions and often trouble with seams in all the wrong places. The leather in these boots is soft enough to have formed to my feet without rubbing and blisters. I keep them waxed and haven't had any trouble with water seeping in. The laces have held up very well, were just a little long. The only complaint, if you can call it that, is that I wish the soles were replaceable as after wearing them for 3 years almost every day, all day, the top part is still good but the soles are now worn out. Thank you AKU, this is definitely my favorite boot. Btw, the Minimas are very comfortable as well.
