This is the third pair I've had in the last 4 year...I wear them for work they hold up pretty well. The first pair I ordered were 9 1/2R. They were abit tight. The 2nd two pair I ordered 10Ws. They fit perfect. Relieve all my foot pain due to Plantar Fasciitis.

Following other reviews, that the shoe is a little small, I took the 5.5 (36EU) and it fits perfect. This is my usual size in boots - to have enough room for thick socks.
I got the red which is amazing dark red. The shoes are beautiful and comfort. Love it!

Perfect fit. We've ordered this shoe three separate times and each time my daughter said it was tight in the toes until the shoe got stretched out. This time I ordered her a 9-Wide, and the fit is perfect. I wish I had thought of this the other three times. She has to wear this type of shoe for work and it's perfect because it doesn't have any colored logos or designs, it has to be all black, per HR guidelines. Very sturdy shoe.

This is my 3rd pair of these shoes and I can depend on the fit. I never have to "break " them in and they keep their shape very well.

I am a true 9.5 and these fit perfect, but I have a very narrow foot which is why I like these. I have 3 pair. The black is my favorite.

Different people have different running shoe requirements so I can't say these are for everyone. They're perfect for me. This is my 3rd pair since the 993's came out. I used to get the 992's and Asic Gel Kayano's before that. This will be the only shoe I get until they discontinue the model. If you wore 992's or Gel Kayano's (before Asics ruined them around 2005) then you'll love these.

Love it it so much I bought 3 pairs. A grubby pair for the barn/outdoor work and two nice pairs for daily use. Ive been wearing orthoheels for about a year now and my feet don't ache nearly as much as they used too. It took a little while to adjust but once I did, I can wear any shoe within the brand with no problem now.

I love these, which are my third pair. They are very durable; I wear them every day for the 8+ months of warm/hot weather we have here. I basically wear them until they are shredded. And then wear them some more...

I have a high arch, so regular, cheap flips won't do.  These offer the right amount of arch support for me.
