I've been a fan of Clark's Sandals since they were still made in England.  Now, even these are made in China.

Still, these are almost the most comfortable of all the Clark's sandals I've ever owned.  They would have been THE most comfortable, it the back strap were adjustable as in the good old days.  I just can't snug the straps as tightly (or easily) as with previous model.

I'm sure Clark simply found a way to take cost out of the equation, at the consumer's expense (at $125 these are still pretty pricey!)

For what it's worth, Dunham has a very similar sandal, at a lower price, with adjustable rear strap.  It's just a smidge heavier than this pair, but a good alternative.

Either way, you won't be disappointed.
