Comfortable foot bed, but loose in the strap

Ever since the Supercoil 3 was discontinued (bad move Oakley), I have struggled to find an Oakley flipflop that I truly like. These 15's were very close. They have a comfortable sole, nice arch support, but....the top strap is too high over the foot bed creating a very "loose" fit. You feel like you have to concentrate to keep them on your feet when walking, otherwise you'll step right out of them. If they would shorten the thong strap a tad bit, pulling that strap down to create a slightly tighter fit, these would be awesome.

These sandals are super comfy and I love the style. The one problem I encountered with these is the strap that goes over the top of my foot is a bit wide and so my feet have room to move around. I have found myself needing to re-adjust and slip them back on/in place a few times. Overall, cute and comfortable sandals!

Comfortable  but straps tend to loosen easily.  A Replacement of the upper straps and these are a five star rating

Very comfortable with a pillow like feel. Not great for a lot of walking though. My feet move around making me feel like a might trip. This is due to the fabric of the straps which seems a bit on the loose, soft side. I am use to a leather strap on my flip flops so it may just be me.

The foot bed is perfectly sized for the length of my foot. The straps are a bit loose, but I have very thin, narrow feet. Still comfy!

I've had several pair of these sandals and really like them.  However, the tightness of the straps varies with each pair.  This pair just happens to have looser straps than the last.  Still find them comfortable.

These are incrdibly comfortable shoes, which is exactly what I was expecting from Merrell. While my foot fit perfectly in the sole, the heel strap (which is adjustable) was too large, even when tigtened to be the smallest possible.

I have problems with my feet and wear Danskos almost exclusively. I have two pairs of the Velcro strap sandals on the same footbed. They are extremely comfortable, so I thought I would give these a try. I have a very small instep, so these are a little wide. I wish they had an adjustable strap. I also wish I had heeded the warnings of those who mentioned the problem with the toe post.  The first time I wore them, they were ok. When I tried to put them on the next day, they hurt so much, I couldn't wear them.  So, my rating is based on the comfort of the footbed (high) vs the comfort of the toe post (low). I am hoping they break in, because they are very attractive in the black leather.

UPDATE:  I waited about a week to wear these again, and I added a layer of foam padded moleskin to the inside of the strap.  Now that they don't move around on my feet quite so much, they are more tolerable.

These sandals are very cute and comfortable.  They have a lot of cushion in the footbed.  However, the leather footbed is slick and my foot slips as I walk in the sandals.  I ended up putting a "ball of foot" cushion in the sandals to give my foot more stability.  It works great!

The straps on these are a too loose so the don't fit on my foot properly and it's easy to slide out the side of them.  I'm a little worried about twisting my ankle.  I am normal/average height and weight, size 7 and they are too loose.  They are comfortable and look cute, but...

Due to the stretch of the material the foot bed/base of the sandals can slide around under my feet. But these are so comfy, I still wear them often despite that flaw!

I love how the footbed hugs my foot. They will be super comfortable once broken it, the ankle strap is rubbing against the arch of my foot.

I like the shoes footbed and front fit. I dislike the back strap being Velcro. If it were a buckle like the front part of the sandal then the fit would be great, as it is my foot slides. The Velcro prevents the sandal from cinching up properly

I love these sandals, and this is my 3rd pair.  However this one the foot strap was different from one sandal to the next; the right sandal the strap was noticeably tighter than the left.  Hoping it stretches out, but for the time being it's rather uncomfortable.

The sole is comfortable and I like the look - nice upgrade from foam flip-flops for bringing the kids to the pool - but the strap is just not quite long enough and pulls between my toes. (I have tall feet.) Hoping to stretch them out with hot water because I really want them to work!

All straps are adjustable, but they don't stay adjusted.  Toe and strap over the ball of the foot will tighten as I walk.  Also, the foot bed rubs blisters on the insides of my heels.  I think this is just the way Chaco's are designed.  Wish these were more comfortable as I really like the design.

Adjustable straps allow for fitting my slim width foot. Footbed is supportive and comfortable. Gave 4 stars because strap edges rub across top of foot some, but not too bad. Wore on walking vacation and had no problems.
