I haven't had these Rider's long and thought at first I would have to send them back.  One foot fit a little different than the other.  It had to do with the strap being fastened a little different or something.  Anyway, it bothered one foot some.  I guess when you're used to flip-flops, well.  So, I'm used to them now and I really like them and enjoy wearing them.  I doubt I'll go back to flip-flops.  The Rider's fit so much better and hold to your feet better if you know what I mean.  They seem durable but, I'm yet to get them wet or spend much time outside with them.  If they don't hold up to my liking then I'll be back to update this review.  Until then, I like!

UPDATE:  Today is March 2, 2016.  Guess what I'm still wearing as I write this review.  That's right, the same Riders that I bought 3 years ago.  I've been retired for the last 2 of those 3 years which means I've spent a little more time in them than the first year.  I wear them inside and out although the outside portion is just around the house.  These are NOT for working in.  I suppose the reason they've lasted this long is because I don't do anything in them but walk around in my space only.  Another reason is because I get the most out of anything I buy.  These Riders are SLAP WORN OUT but I continue to wear them.  When the time comes I'll probably buy them again but, I'm sad to say, they are at least $10+ more than they were 3 years ago and also have different sellers.  All in all, I've been well pleased with these sandals.
