I got in both colors. The leather is slightly stiff in brown color somehow. And it takes few wear to break-in leather, more I wear, it became comfortable. There is very little arch support. If you need one, you have to insert insole to support your arch. The comparison between La Canadienne vs. Blondo is (I own both boots) where it's manifactured (China or other country).  Both of them are waterproof, La Canadienne leather is alittle more softer than Blondo, Blondo boots needs to break in, La Canadienne does not need to time to breack in. The price is $199 for Blondo, $398 for La Canadienne.

The lightest shoe I have ever worn. Not much arch support though and I have to use my arch supports.

It's quite comfortable - good support for the arch; the back strap can be a little softer, but may get more comfortable with regular use.
It looks pretty good too for casual wear with dress or pants.

A little snug at first but fits fine with a little wear.  As others mention, there is no arch support if that is what you need.

After wearing the shoes a few times, the material softened and the shoe became comfortable.

Not a lot of arch support. These are also very thin feeling. I purchased these for the gym but they would not be my everyday show. They are definitely a lower profile type of gym shoe and the arch support is just ok

Comfortable, small profile, good construction.

I normally wear a size 11 C/D, and have low arches.  There are 4 problems with these shoes:
1. The shoe is 1/2 size too short, as my toes barely touch the front of the shoe.
2. The shoe seems to be a bit narrower than expected.
3. The shoes are fitted with wide flat athletic style laces, which are hard to adjust, and too short once the shoes are re-laced to adjust to your foot. (The supplied laces are 45")  I replaced them with 53" round athletic laces which are easier to adjust and tie.
4. The insoles for the shoes are flat and do not provide any arch support.  Replaced them with thin insoles with built-in arch supports.
Once these adjustments are made, the shoe is reasonably comfortable. Other Merrells have been long lasting shoes, so I expect these to be as well.

Update 5/7/15:  I reordered another pair (1/2 size larger).  Once again I went through steps 1-4, and now the shoes are pretty comfortable.  I used the original laces and the insole in the "smaller" pair, and donated them to a local charity.  Living in NC, I feel that these shoes are good for use in early spring, late fall, or during the warmer winter months, but not for hot weather, as they don't really breathe.

I ordered these shoes mainly because they were only $20. Once they came in the mail, I tried them on. They were a little smaller then I expected a size 8 to be, but after wearing them a couple of times they stretched a little and became much more comfortable. For $20, I am very happy with them and surprisingly quite comfortable.

Ok so I said it doesn't have good arch support, it has a little, but they are still comfortable shoes.

These are ok.  They provide very little in the way of foot support or comfort.

Not a lot of support, but a good insert like Superfeet does the trick.

Like being barefoot, but with a little protection for the bottoms of your feet.  The amount of arch support is minimal.  Being that these are a little hard to find sometimes, this was a nice purchase.

Very basic. Comfortable. No arch support. Fits like a convers.

It took about a week for my feet to get used to them. My right foot small toe would rub on the stitching making it uncomfortable for a few days but after I broke them in they felt great. Almost like wearing regular tennis shoes. I have bad ankles and the cushion on these boots was just fine to help me walk for hours with them on.

I was looking for something to help with my Plantar Fasciitis.  This does a great job.  It provides very good arch support.  However, the straps are a bit short and when I put them on to make them comfortable, the Velcro barely touches..
