Update: The squeaking magically went away a couple days after I posted this review, so I've upgraded from 2 stars to 3 stars.  If it stays away for a few weeks, I will upgrade to 4 stars.

Side note: I did purchase a pair of Merrell World Eras locally (my size not available on Amazon, meh) as an alternative pair in case these Clarks start misbehaving again.  The World Eras are essentially the newer model of the shoes I was replacing with the Clarks.

Original review:

I bought these to replace a pair of Merrells for my everyday office shoes.  Merrells typically last over a year before they start falling apart and are very comfortable, but I couldn't find the same style in my size this year so I decided to try Clarks.  They seamed to have great reviews here and everywhere else.

At first, I was very pleased with my purchase of these Clarks slip-ons.  They are comfortable and appear very well constructed with a nice business-casual look.  However, after only a few days of wearing them, the left sole has developed this very annoying squeaking noise that is very loud when walking on hard surfaces but can still be heard faintly even when walking on carpet.  I took the shoe off and bent it with my hands - which results in the same loud squeak - to try to figure out what was causing it.  I believe it results from the two different types/colors of rubber on the bottom of the soles rubbing against each other at the ball of the foot.  I'm guessing it's a manufacturing defect with the two different colors of rubber not adhering together properly.  Anyway, I haven't seen any other reviews with this issue, so I have no clue if anyone has found a solution.  I'd love to return these, but I already tossed the box and I highly doubt the seller (Shoe Mart) would take them back after they've been worn.  Obviously I'm not going to rush to judgment on Clarks over this single purchase, but I guess I'm going to have to find a pair of Merrells I like since I've owned several pairs over the years and trust their quality.  Maybe I'll give Clarks another shot at some point, but I'll look for a sole with a single piece of rubber.
