I love Clarks shoes.  I know what size to buy, even on line, and they are always very comfortable (eventually).  I say eventually since they all come a little tight for me in width, but within a few months they are perfect.  And after 3 - 5 years, they are downright loose and have to be replaced.  I especially like Clarks slip-on shoes since that's the kind of guy I am, but I always put these kind of shoes on with a long shoe horn.  Yes, as one person mentioned, these shoes are a little tight on the top of the foot at first, but this is the way all Clarks slips-ons start.  And since these particular shoes are waterproof, I would expect them to be a little stiffer than the others.  After a few months, these shoes will fit like a glove, just like all of my other Clarks slip-ons.  What sold me on this particular style was the looks and the bargain basement price.  Maybe because this style is being phased out.  However, in a few years, I suspect that I will regret not buying a second pair to replace these.  I was originally after the nice looking Wave Quest GTX from Clarks, but at $160.00 a pair, I'll wait for them to come down in price, maybe next year.  I'll do an update if I feel differently about these shoes in a month or two.  As an aside, I was only able to get these from the vendor called &#34;What's Hot&#34; and they sent me a pair of shoes that didn't even come close to matching.  Thanks to Amazon, the return and replacement was a breeze, but be carful when ordering from this vendor.  They are probably OK, just an absent minded employee.<br />Update: 11/8/15 - These are now my most comfortable shoes, as expected after break-in.  Yes, at first there was some tightness across the top of these shoes as a few have mentioned, but this is normal for well fitting slip-ons.  The advantage of a slip-on is no laces to tie, but the disadvantage is that you have to use a shoehorn to get them on easily, especially if you want them to fit like a glove after break-in.  Slip-ons that are too loose don't support you foot very well, especially when walking down hill.  Love these shoes now.  Might just buy another pair for when these wear out since the price is right.at are too loose don't support you foot very well, especially when walking down hill.  Love these shoes now.
