I recently purchased a pair of Wool Runner Mizzles from the AllBirds site. The size I chose fit me perfectly (I'm usually a 7.5 or an 8, and all of the AllBirds size 8s that I ordered fit me perfectly). I took the Mizzles out for a trial stroll around the neighborhood, and it only took 5-10 minutes for the back of my heels to start feeling violated. I was wearing a pair of thick black socks, too.

When I got home, I inspected the backs of the shoes. No wonder I felt like my heels were getting shredded -- the threads used to sew the plastic protectors on the back of the shoes are all exposed. There's at least an inch of horrible thick threading back there, fat enough that I could feel it THROUGH MY SOCKS.

I immediately ordered a pack of Dr. Scholl's heel liners, and applied them to the backs of my shoes. Instant relief.

Other than this glaring design flaw, I love these shoes. But, AllBirds, listen up, if you need to sew a plastic protector to the back of the shoe that badly, at least cover your horrible sewing job! These threads are chewing up people's heels. Personally, I don't think the little piece of plastic is more important than wound-free heels.

Here's hoping that AllBirds gets this memo.

Everyone else -- if your heels are getting chewed up when you wear these things -- it's not you. It's these threads!
