I tried 4 different pairs of the 801's, in four different sizes, and none of them fit, all were uncomfortable for different reasons. The length seems right for the sizes, but the D/Medium width is skin tight and smashes toes, the 2E is a little better, and then the 4E is very, very wide. In all of the size variations, my front toes smashed into the sides and/or front of this shoe. If you have semi- wide feet such as mine (E width), this may be hard to fit. The D and to some extent the 2E are narrow due to the design, and the 4E is so wide that unless you have truly BIG WIDE (4E-6E) feet, your foot will probably smash forward, into the front of the shoe. This shoe is VERY good at letting your toes smash into the front and sides of the shoe.

I think the huge expanse of elastic over the top of the shoe is a big part of the problem, plus it just seems apparent that not much fitting/ergonomic design went into this shoe. I have worn more than a few 2E and 4E wide New Balance shoes over the years that fit great and are delightful; not this one! I really wanted the 801's to work--this shoe is ideal for running errands and for walking the dog, but it just didn't work for my foot.  The final pair I received (12.5 2E) is going to the Goodwill; I tried to endure with them and make them work, but after only a few dozen yards, my feet still just scream to get these toe smashing mightmares off!
