I have tried Okabashi Maui, Ocean, Surf and Eurosport styles.  The Maui style is very comfortable and lightweight.  I am a female, so this review may not apply to all viewers.  The Maui style is a very comfortable everyday thong sandal with moderate arch support and reflexology beads. I don't recommend the Ocean style since it has two-part construction and it broke at the thong part after very little use. The men's Eurosport (slide) feels comfortable at first but appears to be lacking in true support and firmness - it is a "cushy" style with excellent traction, but not the best overall support for long periods of wear.  The Eurosport model is fairly wide, so that may be a reason why over time it provided less support.  The Eurosport model also seems to stretch almost immediately after you wear them.  I haven't worn the Eurosports in a while now. There is just no comparison to the Surf sandal.

The Surf sandal is very firm with a solid, gripping bottom - it offers a lot of bang for your buck.  You can find this at some CVS stores for $12.99. I bought the Men's L (men's 8.5 - 9) and it fits almost true to size for a women's size 9.5.  This model has the most arch support and ball of foot support of all the models that I have tried.  This is important if you plan to walk long distances on uneven surfaces.  The firm raised ball of foot area seems to help lessen foot fatigue and it also seems to keep my feet aligned and properly positioned.  As compared with the Maui style, the Surf sandal has a wider footbed and a thicker and more rugged bottom - great traction.

This style is also fairly attractive.  The brown sandal with etched thong looks somewhat "tiki" and tropical and these sandals are not "glommy" at all (my word to describe big, awkward and heavy shoes).  They fit comfortably and offer firm cushioning.  I now have them in brown and black.

I compared the Eurosport Men's L with Surf Men's L, and the Eurosport size L is between a 1/4 and 1/2 inch longer than the Surf model, size L.  That would explain why the Surf model is a better fit for me.  I have arthritic toes and the raised toe bed, ball of foot and arch support seem to really help keep my toes aligned and resting comfortably.  The less supportive and looser-fitting Eurosport model on the other hand did not provide any support for my toes, so consequently I experience foot fatigue and pain after wearing the Eurosport model for an extended period of time.

I could live in these - these are absolutely the best sandals out there for standing long periods of time!
Like any thong sandal, they aren't the best for walking for hours, but they'll do for short walks.

Hope you like these fantastic Surf sandals!

Just yesterday I wore these all day - standing much of the time - and I can strongly recommend these sandals for hours of being on your feet.  I experienced no fatigue at all.  They are amazingly foot-friendly.
