My significant other used to wear the Columbia brand hikers that are visually very similar to these but they were discontinued. We found these after trying other "waterproof" Columbia hikers that were just NOT waterproof. These fit him the same way the Columbia hikers do but with little to no break in period. They are truly waterproof. They are warm enough with insulated socks in the winter (he works outdoors and on rooftops in the cold midwest winters) and cool enough for warm (70 degree) weather.  These were purchased in December and his only complaint is that, after nearly 5 months of daily wear in unforgiving conditions, is that the sole is making an odd sound almost as if it has an air leak.  Which is really nothing in comparison with other hikers that we've tried for him that have no tread left after 2 or three months of walking around on rooftops.  These hikers still have half to three quarters of the tread remaining and we think he will be able to get another 2 or 3 months of daily wear out of them!
