      Something's changed at Florsheim
      Size: 11.5 Wide, Color: Black
      I have a pair of size 11W Florsheim Palermo loafers that have lasted over 8 years and are still soft and exceptionally comfortable. Ordered a pair of 11W Florsheim Milano on Amazon but they are too small and have a cheap plastic sole. So, ordered 11.5W Florsheim Berkley and they were way too big. Returned them and ordered 11W Berkley instead and they were also too big ... and the Berkley also has a rubber sole instead of the original leather shown in the product photos. Guess they just don't make them like they used to.

      Beware of the Brown Crazy Horse version.
      NOTE: This review is COLOR SPECIFIC and concerns the Brown Crazy Horse version of this shoe. I am a loyal Florsheim customer having purchased Florsheim Imperials in years past. They are a fine shoe. However, I have to admit complete frustration with the Florsheim Berkley Flex Penny Loafer in "Brown Crazy Horse." The photos in the listing show a shoe with gloss...a shine. The photos on the box show a shoe with shine. Don't believe the photos. "Brown Crazy Horse" is, at best a dull matte finished leather. If you want a classic penny loafer with the classic Florsheim look this is NOT the color to choose. When the shoes arrived and the shoes did not match the photo on the box, I ignorantly assumed it was merely a case of the wrong shoes in the box so I exchanged them for another pair, which was a big mistake. It is Florsheim's incorrect photo and box label that caused me the inconvenience of going through two pair and then having to return both. I would assume other colors are as pictured in their listings because I cannot imagine that every Florsheim Berkley Flex Penny Loafer is a dull matte finish. I'm sorry that I do not have photos of the dull finished shoes. You'll have to take my word for it. They are a matte finish at best.

      Just right, great quality and value (in the price)
      Size: 11.5 X-Wide, Color: Burgundy
      Exactly what I'd expect from a Florsheim. I'm delighted. Folks, let me share one mistake I made on my way to a good fitting pair of shoes. I ordered some in my size (I have a big foot, especially in width). I ordered what I thought I needed and it came in wide enough, but too short (the short was the surprise), but we all are told: "Manufacturers vary in their sizes not only from each other but from shoe model to shoe model." I want you to know I believe in that when it applies to clothes, especially children's and womens fashions in my life's experiences, but NOT with shoes, especially main-brand-deluxe. I ordered the next half-size up and now I have too large, how can that be? I found out when I pulled the paper stuffing out, in particular the LAST glob that extends from the middle to the toe, that it WASN'T the last glob, there was indeed a rather small glob still way down in the toe, almost pointless for this minor bit of stuffing being separate from the other, but it was. I had already innocently troubled Amazon with returns of shoes that would have fit, so I'll keep the half-size too large as a life lesson. I ordered this pair in the size I believed I was all along and viola, a good fit. What changed? When that last toe piece of paper wadding that's hard to see and even harder with a big hand to reach, the shoe fit perfectly. That's a lot of trouble because of a small piece of paper that was hard to see, but that's why I write this review for you so that you can make sure all the paper is really out when you already think it is. Amazon has been good enough not to hold me accountable and in return I'll not only repeat buy, I tell you of my experience.

      Great price great shoe
      Size: 12, Color: Burgundy Polished Full Grain
      Excellent shoe. Tried the Sebago penny loafer and the sizing was ridiculous. These J and M are sized perfectly. I’ve had them before and they wear like iron. Very comfortable right out of the box.
