No arch support.  AT ALL!!!  BEWARE!.I added my own but my foot slips sideways in the shoe., a fall "waiting to happen" Maybe the flat version will work better with an arch
support.. I do not recommend these for anyone..

I gave the 1 star because they look great on your foot...

Definitely not for really flat feet.  The inside is completely flat and the sides are too low to provide adequate arch support.  There is no heel cup to provide stability - it's just completely flat inside. I get better support from my Birkenstocks.

I have flat feet, so arch supports are not comfortable.  These shoes are flat bottomed, so I like that.  But, there very little cushion for old feet.  Still not bad for the price.

My daughter likes these shoes. They are very flat so we added arch supports and it is better.

NOT for the flat footed, but you probably already knew that. I had to get them for my wedding. They worked as intended, but I paid for it the next day.

Appropriately wide, lacking a bit in arch support.

Feels a tad on the flat side, could use a little more contour to hold the foot better.

These are one of Dunham's more stylish boots. The leather is wonderful, but the actual color is a bit darker than the current photos. I was a bit disappointed by this, but still they are very handsome. They're fairly light weight and  flexible. Sizing seems true in both length and width. Comfort is good, but they offer very little arch support. Even with after market inserts, they just don't offer much support and tend to roll from side to side. My Dunham Outlook's are so much more supportive and comfortable on long hikes. Basically you're trading in support for style with these. They are a nice shoe for less active use.

I've purchased two other pairs of Tsubo shoes in the past and really liked them.  This particular pair, however, doesn't provide the same arch support of past pairs.  This could just be inherent to the particular shoe model, or the direction where Tsubo is going.  Regardless, the shoes are relatively comfortable, but I wouldn't put them on after wearing another style of shoe with good arch support, you'll feel the difference.

This is hard because every foot is different.  I needed extra support because my flat feet were hurting.  I guess you'd say fallen arches, though my doctor didn't use that term.  He sent me to a local store for Superfeet insoles.  I determined that Blueberry ones were right for me, but i wanted these flip flops for times when I didn't need to wear serious shoes.
I find that the flip flops correct less than the Blueberry insoles, similar to the black 3/4 length one I tried at the store.  For my feet, they are not corrective enough.  Better than nothing, but not as good as I'd like. But again, every foot is different...
The sole is hard, and if I wear them for a long time, sometimes the ball of my feet start to complain.  I wouldn't wear them on a hike.
They are great for wearing around, though, and much better for my sore feet  than regular flat shoes.

Arch could be more solid. I bought arch supports and they worked fine Comfortable and sure footing this is a great boot.

The arch support question is silly since I bought these shoes to have a zero drop flat footbed. Although there is the tiniest bit of a curve at the arch, which I would prefer not to have, but it is okay. These shoes feel wonderful when I slip my feet into them, but as soon as I start moving I notice the toes rub against the front a bit. I'm hoping they can be broke in a fit well. But I do prefer shoes that don't really require breaking in. But it's so impossible to find a shoe that is flat and good for my spine while still being cute and functional, so I guess I have to be satisfied with very, nearly perfect fit.

I have arch problems and weak ankles and have been instructed to wear wedge heels. I usually take several years to warm up to fashions, and it did take me a while to like this idea.  But I really like them. I treated to material before wearing, but have had a lot of rain lately and have gotten a little mud on them, but they seemed to clean up well. My husband says the make my feet look really little - which I like. The foot print is really small, and I have bent my ankle a few times walking on uneven surfaces.

Unfortunately, will try to send back. I've worn them less than 10 times, and the sole is coming off the heel.

These aren't as comfortable as I would have hoped. I have a high arch, and the arch of the shoe is mire flat, so there's very little support. Cute AF, though.

I would have preferred a bit more arch support, but this shoe would be find for someone with healthy feet

I really want to like these slippers.  I know they're good for my feet and alignment.  I'm following Orthaheel's suggestion of wearing them for just a few hours a day, for a few days.  I've been doing this for about a week, and there is a larger level of comfort while I'm wearing them now, but there is a very hard (wooden-like) arch support that mostly hurts.  Those supports seem to hit my feet at different points, on my right and left foot.  I still have not made up my mind as to whether I will keep them or not, so, I haven't thrown the boxes, or paperwork away yet.

Let's just say, "We're dating.  I'm not yet ready to commit."
