Injured wearing Endorphin Speed

The Speed is by no means a stability shoe. Its high stack, soft peba foam, & medium width base are no match for someone with abnormal movement.

Tell us about your most recent gait analysis.

My gait is fine, run in neutral shoes all the time and spend a good of my time in Altras. This is the first time I’ve had this issue with a shoe.

Just clocked 400 miles in my first pair and onto the next. I dont think the shoe is the issue on this one. These are hands down the best shoe ive ever run in, on all levels.

Just got a pair. So far they are my favorite shoe, I would probably ditch the VaporFlys and go to the Pros if I didn't have two brand new pairs of VFs in my closet waiting to be used.

For what it's worth I'm 40, 5'10" 130.

If the shoe doesn't fit don't wear it. No need to overthink it.

It's actually pretty firm. Much firmer than ZoomX.

I agree.

The Speed is certainly not "soft".

I found you have to break these in a bit if you have slim feet. It is a little hard to get a good foot hold when they are new and I did a 10k tempo in them for one of my first runs and had the same issue, my feet sliding forward. I really didn't notice while I was running how much my calves were getting worked because of this and while I didnt get injured I was a lot more sore than I should have been or would have expected. Since then I have just made sure to really get them locked down prior to doing any fast running in them and they have been great.

Read the RW article on wearing carbon shoes for training. It DOES change mechanics for some people to the point one may get injured.

A majority of people really like this shoe. Anecdotally, I've heard of someone who said the shoe has allowed them to run pain free where their previous shoe had been aggravating a tendon issue.

Sound like the shoe just isn't for you... oh, well no big deal. Cut your losses and move on. No more discussion needed.
