Berkies all the way. When coins were tight I tried some cheap Berkie look alikes, they are not the same.
Trouble with Berkies is the expense, then they are pretty fragile, don't go wading in them, don't climb ladders in them, don't let the soles wear to thin. Lots of don'ts and if you slip up you can trash a pair in a hurry. I have been wearing them for about 25 years, and have trashed several pair, so those don'ts are pretty much personal experiance. I think the fact that I weigh 240lbs tends to shorten the life a bit also. I need to resole them about every year. But they are heaven on feet!
