Speed 2 v Speed 3

I can only speak for myself, but I picked up a case of posterior tibial tendinitis while running in the Endorphin Speed 2. I don't think it was the root cause, but it did exacerbate it; the 2 is a pretty unstable shoe for me in the heel.

The Endorphin Speed 3 is a totally different story for me. A little firmer and doesn't have as much of that dramatic roll, but a LOT more stable and felt better at all speeds for me. A much-needed improvement.

I have the Endorphine Speed 2 and i have to confirm that this shoe is my most injury risk shoe i have in my whole collection of different brand shoes.

Very unstable and i do not recommend it.

Whoa. Interesting. I had PTT pain pop up on Jan 1 in my FIRST run in the Speed 2s. I was super excited to run in them and made it maybe 200m from the house and walked home.

Hmmm....correlation or causation?

Since then ive ~recovered and love the Speed 2 for faster sessions.

Maybe it just exposed some weakness i already had from too many sessions in another shoe. That was my thoughts initially.

There should be a Running Shoe battle about it somewhere on YouTube

For me personally I thought it was the speed 2s that was causing my achilles tendonitis but I experienced it with other shoes as well and concluded that the cause was hilly long runs aggravating the pain. For a few months it was recurring and very painful even with regular icing but ever since I took time off after track it's usually been minor and goes away either with rest or icing.

If you're prone to shin splints and PF better to stay away from the Speed 2s. There is no doubt that it was the shoes that caused the problem. I avoided them for a few weeks and was running pain free. One single run with the Speeds and the pain was back again.

It's a shame. One of my all time favorite shoes.

Hi,

I have the speed 1 and 3. The 3's are softer, more comfortable and stability has improved quite a bit. I find I enjoy the 3's more as more versatile at various paces. The 1 may have a very slight advantage at the fastest paces as the rocker seems more pronounces and nylon plate stiffer but the comfort levels and stability and wet weather is superior in the 3's. Its also great at faster paces too.

The Speed 1/2 never disagreed with me really. If I was going to say anything, it is that the Pro can wreck some shins. My pair are a half size too big, and putting that awkward landing together with the very stiff and tall stack was not good. Lots of lower leg pain and awkward striding unless I hammered the pace.

The Speeds I have in the same size as those Pros? Made it to 300 miles without any discernable issue.

Endorphine Speed 2 I do not recommend, too many injuries
