I bought these slippers several weeks ago and took another reviewer's advice and ordered them a size larger than my shoe.  They fit fine with about 1/2" to 3/4" space at the big toe. Due to the design (and my wide foot) my toes don't travel forward, and my foot doesn't travel inside the slipper .  My normal shoe size is a 14 EEEEE and I ordered these as 15 EEE.  The slippers were a bit stiff when I got them but got soft in a couple of weeks of wearing. I'm wearing them now, and they feel fine.

...April 2013 update to above Jan 2011 Review..Lowered from 4 stars to 2 stars:

I've had these slippers for 27 months and when I bought them I wrote the above review which was originally 4 stars. Maybe I'm expecting too much from a $42 pair of slippers but as these slippers reached the end of their useful life I realized why the leather is separating from the seams and why the toes and heels have opened up and are spilling stuffing all over the carpet.  The reason is that the slippers are actually composite felt slippers with a covering of micro thin leather.

The actual leather that covers these slippers is thinner than the thinnest paper. As they age this leather coating breaks away from the top, side and bottom seams and starts to separate from the felt. It's also the reason that if you use them to get your mail, contact with a concrete walk will scuff the leather right off the felt.

I don't know if Evans slippers were always made this way, I've been buying them since I was a teenager. But this is the last pair I will buy.

I'm presently waiting for a pair of all leather, leather lined moccasins with smooth leather soles to arrive to replace these slippers... They cost 3x as much, but I'm hoping they last at least 3x as long.
