I work in film and sometimes work for weeks, and months out of town on location.  I was looking for a comfortable, waterproof, boot that I could wear both on set and on location.  If I can find one shoe to do both it saves me space in my luggage.  I noticed some of the guys wearing this shoe, so I asked them about it.  The shoe fits the bill.  The sizing-is european so if you can go to a shoe shop to check your size, that may help you from returning a pair that does not fit.  I had people who I could compare my size too. So I was able to fit it on the 1st try.  They do stretch a little so keep that in mind.  Otherwise I was able to do a full 14 hour day in rain up in the Bodega Bay area in uneven footing no problem.  My feet were warm, dry, and comfortable.  One of the most useful things I have purchased in the last five years.
