I am a medical professional and am on my feet for many hours of the day.  I was looking for a clog that had great ventilation and was comfortable for someone like myself that had flat feet.  In the past I had used a clog that had an open heel and did not like the sensation of constant heel "clapping" as I walked.

I decided to try out the Yukon.  At face value it had everything that I wanted and in all ways but one, it actually delivered.  The ventilation is excellent-feet do not get hot at all.  The adjustable heel strap works great and while there is some elevation of the heel when you walk it is hardly noticeable and after a while it feels like a closed heel even though it is not.  The style of the clog is a "step-up" from your "run of the mill" clogs.

The only criticism I have for this clog is comfort.  The problem is the foot bed consists of a hard rubberized sole that has nubs that project upward that is designed to help circulation and message the foot.  Unfortunately all it did for me was make the otherwise perfect clog into a uncomfortable clog.

I absolutely agree with a previous reviewer's (Jared) comments that these clogs "are not bare foot friendly and worn without socks will murder your feet".  I will go just a bit further than Jared and say that even worn with socks your feet may not be torn up but it is certainly not as comfortable as other clogs that have a soft cushiony feel. Arch support was also minimal.

Fortunately for me the local sporting goods store ("Dicks") carried these clogs and I was able to try them on with some cheap orthotics that when inserted into the clog not only covered the rubber nubs but also provided the soft cushiony feel I wanted with better arch support.  All the problems were solved and now I have the perfect clog!

For those of you who have the same concerns and wish to follow suit with my solution please be aware that the orthotics take up space within the clog ( unlike clogs made by "KlogsUSA" which have a removable sole that can be interchanged with an orthotic).  I wear a size 8/12 tennis shoe.  With the orthotic in place I bought a size 10 clog.  Last bit of advice: if you buy an orthotic to cover the nubs buy a full orthotic that spans the entire clog from toe to heel because the nubs extend the entire length of the foot.  Hope this was helpful.
