I had a pair of Tree Runners for a couple of years and wore them every day. I have never had such a comfortable shoe. So it was a no-brainer, once they got a bit ratty and holey, that I would get a new pair of the exact same shoe (size 7W).

It only took a couple of days for me to receive them, which was super impressive. But these new size 7's were much larger than my original size 7's that I bought only 1.5yrs earlier. I checked the labelling, and my old and new pair had exactly the same specs. I asked AllBirds if maybe they had changed manufacturer since they went public, but they insisted they hadn't. As a manufacturer of my own brand of products, I understand these things, and I knew that was a possible fib. At the very least, the labelling had to be wrong, which can easily happen during production. Anyhoo...

I returned the size 7's and got a pair in size 6, but once they arrived, they were too tight!

At this point I figured I'd have to suck it up and re-buy the size 7's again, and tie them up extra tight so they won't slip as I walked in them. However, when i got this new pair, they were a perfect fit, just like my original, old worn out ones! I am convinced that the first 7's I bought this time around were labelled wrongly, or they have lost all quality control in manufacturing.

Anyway, I was just happy that I got the right size eventually, and since AllBirds insisted the whole time that there was nothing wrong with the size - despite the fact that there was - I knew the problem wouldn't be looked at, and others would just have to go through the same mess I did.

BUT, it's been a few weeks now, and they are nowhere near as comfy on walks. I always try to walk between ten thousand steps and 10km each day, and never ever felt the ground beneath me with my original AllBirds. I could walk forever, which is why I loved them so much!

However, with my new AllBirds, my feet were hurting from the first walk, but I kept persisting, thinking I just needed to wear them in, even though I never had to before. But several weeks later, it's just getting worse. Not even halfway through my 4km morning walk, and the balls of my feet were killing me. I didn't know how I was going to make it home and was just trying to take each step using different parts of my feet to give relief to the sore parts. As you can see in the pic below, I wore my old pair until they almost fell apart, and not once did my feet hurt in them, ever. And I walk ALOT, and they always felt great - the ground was soft and comfy, like I was walking on air. Not the case with this new pair.

Something is up with AllBirds. I honestly think that since they went public after I bought by very first pair in the pic, they're cutting costs. I used to endorse them to everyone I know, but I think i will have no choice but the try Sketchers (urgh!) since I've heard good things about them. I LOVE the look of AllBirds, as they go great with training gear and jeans alike, so I wore them everywhere before. But I can't now. My feet can't take it!

PS: I forgot to mention that I also never got an email to review my purchase. You also cannot find an option to leave a review on their site.

I have a feeling that if you raise an issue within a certain period of time after purchase, they disable the review request email that you would normally get. As an online store owner of many, many years, I can confirm that review emails are NOT random as someone else in this thread has said as per a conversation they had with AllBirds. Review request emails are normally automatically sent after a period of time ie: 7 days after purchase, then a reminder 14 days later, and a final one after that if a review hasn't been left yet. I told them a few weeks after my purchase that I never got a review request email and they replied with the attached. I still haven't got the email. I am 100% certain that they flagged me not to recieve one as I had the issues mentioned above. This is illegal to do, as they seem to me, to be only sending email requests to those more likely to leave positive reviews, which is deceptive and misleading to potential buyers. You are not legally allowed to manipulate your buyers this way.
