The great:
I just ordered my second pair from Amazon. I got an amazing price. I'm not sure I would have ordered except for the Amazing price.

The good:
These are extremely comfortable and useful slippers/shoes. I love how they fit my foot, how they breath, how I can wear them outside for short jaunts. My feet never feel to hot and never get sweaty as they have in my accorns. My feet stay comfortable even when the weather gets warmer.
Perhaps the nicest feature is how easily they slip on. That encourages me to put them on all the time and to quit wearing out my icebreaker and wigwam socks which are rather pricey.

The bad:
These slippers seem to wear out in the toe more quickly than I feel they should. I certainly don't expect them to wear out in 4 years of part-time-use which is what my last pair did. I kept wearing them for another couple of seasons even with a big hole in the toe all the same, but I expected 6-8 years use for the $80+ cost. Wearing out in the toe in merely 4 years is the reason I can only give them 3 stars.

My Idea:
With "the bad" in mind, I think I will take them to our local tailor and see if I can have a more substantial durable patch sewn into the toe area to prevent wear-through this time. It seems like toe wear is a known issue in these particular types of slippers. I'm not sure why someone hasn't placed some sort of soft yet durable patch in the toe area to give these slippers some longevity. Perhaps I will find out why when I modify mine. I hope to keep people posted with my experiment.
