I bought these 3 years ago and wear them regularly and they are held up extremely well. They fit well and are thin in the right places and padded at the heel and toe. They wore out after 3 years and lasted longer than other brands. Worth the money.

It's the second time I buy these shoes. The last ones lasted for three years, in which I wore them every day during winter (in Chicago!) and even used them outdoors occasionally (to do laundry, pick up mail, etc.). After three years the soles broke, which I think makes sense. Three years for slippers sounds like a good run.

I love these and will be bummed if they ever go away.  I buy a new pair every 2 years or so and wear them probably 8 months out of the year.

I've used these practically every day for the past 2~3 years and they are comfortable and keep out the damaging noise while still allowing me to respond to someone trying to get my attention.  They're holding up nicely.

I wrote a review shortly after purchasing these a few years ago and they've aged quite well. I think it's been roughly 3 years since I bought these, and they still provide high quality sound.
Some things to note:
-I use these almost every day, but I still only need to charge them about once or twice a month.
-only recently they have been cutting out more, for a 3 year old headset thats not too bad. My beats only lasted a year before they started cutting out.
-the noise canceling on these is pretty good. I have had no problems using these instead of other hearing protecting when in the woodshop or firing range.
-I will stand by my previous statement that these are 2x as good as the beats equivalent and for a fraction of the price. Don't pay for a brand name when you can get these.

These socks are comfortable and look good with the pants/shoes/belts I wear them with. I got the three pairs in January 2010, and after three years, they're almost on their way out. They are great socks if you are expecting around a four year life span. Otherwise, look for a higher quality sock.

3rd pair I've owned and I'll buy another when they're worn out.

First pair lasted 3 years. Well made and very comfortable. Would buy them for the third time!

I bought these for special occasions, but my 3 year old often chooses to wear them for daily use.

I have purchased these before and that's why I wanted them again.  They fit nicely and last longer than most slippers.  I wear mine outside in the backyard a lot.  They've lasted for about 3 years so far.  I bought the second pair as a back-up because I know that things become discontinued after a while.

I bought these for the past 3 years. They lasts long and it comes as the sizes they say but not ever the longer ones just the shortest size.

I've been wearing these for years.  This is the third pair in 12 years.  They last about 4 years and I wear them a lot.  They wear out from wear and tear.  Well made and they last.

I have been wearing these socks for years now, but my last few orders have been disappointing. The socks fit just as well and stay in place as they always did, but I have noticed that they are of poorer quality these days. I start seeing holes in the socks where my toes are after a day or two of walking in them. I will be searching for more durable alternatives.

We have had a new pair of these every year for 3 years and haven't been disappointed yet.  They wear great and our child says they keep the feet warm!

Been wearing these for about 25 years and hoping that I live long enough that they come back into style and the price drops.  The quality has dropped significantly over the years, and they seem to wear out faster. But the fit is the same.

I wear the Mark Zuckerberg work uniform of hoodie & flops, with flops as casualwear. What i'm saying is I've exclusively worn these flops almost every day for an entire year, to the point where shoes feel weird. They were comfortable and functional on day 1 and they are comfortable and functional now.

Tiny bits of fake leather came off the thongs, leaving behind the structural nylon which continues to do its job of holding the flop together. That's the extent of the wear after a year.

Bottle opening action is clean but somewhat awkward.

These things get to reek, I just leave them in a bucket with some oxy clean and they're shiny and new.

UPDATE
They lasted about 3 years of wearing almost every day, starting to split everywhere.
