1) Construction My pair seemed to be well built, and light in hand. I did not notice any rips, cracks or other separations in the components of the shoes. They are moderately flexible, more so if you remove whichever of two style inserts yours came with. (More on that, later) 2) Fit The toe box on these is big and roomy, as a good shoe should be. I did notice a tight spot on these shoes, though this might have to do more with my individual physique than with the product: A slightly tighter fit between the inside tops of my feet and the shoes, especially when wearing thicker than average thickness socks. I was able to remedy this with a file bit for my drill, and gently filed away about 1mm of material from inside the top of the uppers of both shoes. I can now still wear them comfortably without socks, or, with socks of any thickness. 3) On the Move: These are NOT Merrells or Danskos! But they are an economical alternative with at least 70 percent of the arch and overall support I need at work, or for a mile-long walk around my neighborhood. I have tested them with and without the included inserts, and have not experienced a whole lot of rubbing in most combinations. For me, if I go barefoot, I will leave the bottom inserts in. With my thicker socks, I can wear them with or without the inserts in. Wearing my thickest Icelandic 30 belows, I can wear them without the inserts, on my leisure days when it is cold outside. I also own Crocs Lite Ride sandals, and can say that Crocs does know 'a thing or two' about orthotic support ergonomics. And it has translated to the experience in these On The Clock clogs. 4) Finally.. The SWEAT Factor! I've read a lot of reviews from wearers who state that their feet got really hot, and or sweaty and smelly in Crocs On The Clock. I would say that is true in my case - but only when wearing my thickest socks - the Icelandic 30 Below wools. After a few hours in the Crocs/Icelandic combination, when I remove the Crocs, the bottoms of the Icelandics are indeed warm and wet! But not squishy wet. And that leads me to my final section, regarding the title of this review... 5) Two Flavors of On The Clock Clogs: I bought, from this page, the version with the dark spongy support inserts with fabric on top, and with small holes punched through the forward(toe box) section for breathability. That might explain my lack of the squishy-squeaky soaky experience I read in so many reviews here. There is another version, which looks externally exactly like mine, top to sole, but, it has the red or orange? insert that is just plain rubber, and has the same pattern as my aforementioned Crocs Lite Ride flip flops. Now in a shoe like these On The Clocks, even with the small holes they do come with, a solid rubber bottom, or insert if that's what that is, is what I would understand to be a recipe for really irritably hot, sweaty soles, with or without socks! And that excessive sweat is what can lead to the squaking, pardon my french, 'farty' sounds of a thoroughly drenched foot against the rubber bottom of such a shoe. I would suspect that most of the excessively 'hot n sweaty' and squeaky complaints are coming from wearers of that version, which I have yet to review. I may be wrong. Please let me know, if there is a reply function to these posted reviews. Overall, for under U.S. $50, they are a relatively light, comfortable, and supportive shoe for, as they are named, on the clock at work, or at home or out on the town. **Update - 2023-March** My two pair of Crocs On-the-Clocks, the regular/originals and the ones with LiteRide insert, are so laid back, semi-formal, and easy to wear that I often just put one pair on or the other without thinking too much about it. Most folks are surprised when they find out these are Crocs! And I have to say that the "non-Literide" black fabric insert version is definitely the sweatier of the two versions. Last week I wore them barefoot to a mall, and walked a few laps around the main concourse, an hour or so before the stores started opening. Even as I arrived at the mall, my feet already felt quite warm in them, and a little damp, even thogh it was only a few degress above freezing outdoors. After half a mile walking(four laps around the main axis of the mall), my feet were squeaking around in them, and my soles felt drenched in sweat. Sounded like ducks quacking with every step, lol! I had to sit down somewhere I could slip them off and let my feet cool off - and dry off! - before resuming my tour of the mall. One of this mall's many sofas scattered through out served the purpose. I guess the fact that these Crocs do keep feet so warm, with or without socks, is a plus in New England or the Northwest, where sub-freezing temperatures are a regular winter guest. So yes, you can wear either version of On-The-Clocks work clogs without socks, but remember, your feet will likely sweat more in the fabric insert(original?) version than in the orange rubbery lined Literide version. So, wear socks with the regular version if you plan to wear them for more than just a garbage or mail box run, longer than an hour, or plan to walk around alot, for work or leisure.
