At first I thought this was the perfect minimalist running shoe, but there are some minor issues. The inner boot is a little small for me to wear with socks. Fits fine without socks, but the boot absorbs like a sponge. If you have sweaty feet like me, running without socks is not an option during the hot months. Especially with this shoe. Might be an issue during rain. I tried wearing just the shell with no socks while running, but my foot slipped around a lot and squeaked while I ran (think wet flip flops). Worst issue was that it created a blister on one of my toes. By the way, this is the way I wear the shoes day to day. Works great as a minimalist casual shoe with shorts. Also good for pool. I've found the best solution for running is to wear socks with just the shell and no boot. Maybe if I had a bigger size, I could use the boot with socks. Although, I wonder if I would be as happy with the shoe overall. Sometimes debris gets in the shoe through the holes, which can be annoying. This has only been an issue as a casual shoe, but hasn't happened while running. I've only run about 70 miles so far in the shoe. My longest run being about 6.5 miles. I run on country roads that are not as smooth as a typical road and sometimes can be as rough as gravel. I was worried about the durability of the shoe, but it seems to be holding up. My past two Saucony CC shoes were extremely durable on these roads, and I'm hopeful the Ultra M will be the same. I literally ran holes in the bottom of my first Saucony CC shoe. Great ground feel for the minimalist runner. Plenty of room in the toe box. I highly recommend giving this shoe a try if you're a minimalist runner. Fortunately, a shoe like this will not cost a lot in a couple of years. It probably only costs very little to make this shoe including the liner.Read more » « Show less August 12, 2011 by Anonymous

Just got the shoes and had to send them back. I ordered a size 13, which is what got shipped; however, their sizes are running too small and the shoes didn't fit. I am very disappointed because I really liked the shoes and they were for my birthday. Too bad they didn't have a size 14. So anyway, order a size up when getting the shoes because they are running small.Read more » « Show less March 13, 2012 by Clayton S
I've tried about 7 different barefoot running shoes and right now these are my favorites. The Merrel are nice, but they do too much trying to keep the shoes mainstream, but I love them for around town. When it comes to running, these are my go to shoes and they are working great. One complaint I have heard is how the shoes do not hold up well to miles and start to break down after 100+miles. I find that a bit more normal for all shoes and not limited to barefoot shoes. I absolutely love these shoes. Only problem is I can't wear them without socks bcs the sweat makes the shoes squeek. I love these shoes.

It is absolutely amazing how comfortable these shoes are. They were very easy to get used to and comfortable from the first sept until now. I do recommend getting half a size larger if you plan on wearing socks. Thanks to reading other reviews, I did that and it worked out great.

If you're a heel-toe walker, you'll quickly start to walk differently while wearing these. I observed that stepping on my heel was very uncomfortable. At first I thought the extra room in the toe box would mean my feet would be slipping around inside, but it actually helps my feet adapt to the terrain. There's almost no cushioning or support, but they're still comfortable. When wearing them in the rain, it's best to take the inner sock out, otherwise they'll just get soaked.

Love these shoes. They are very comfortable. At the time of this writing I have had them for a month or so. I wear them all day long (17 or 18 hours). I have ended up wearing them most of the time just as the cage. I find they make my feet sweat a little when I have the insert in place. I do feel like they are true to fit...I have sen some of the reviews claiming they are not and in those claims they all talk about not fitting with their socks on...you need to look no further than the name of the Shoe to see the problem with those reviews. It's Vivobarefoot, not Vivosockfoot. So far the quality seems to be good. I get asked about these shoes everywhere I go. I never realized so many people looked at my feet until I started wearing these. I have a pretty flat and wide foot, I generally wear a double E width, these shoes are wide enough for me so if you have a narrow foot you might find these a little wide, especially without the insert. I would definitely recommend these to any of my friends, in fact I already have.
