Are the Saucony Endorphin Speed worth it?

Personally I love the speeds. Softer than a carbon plate shoe but still gives you a bit of pop for tempos or even racing. Look out for deals on the older versions, I picked up two pairs of the speed 2’s for $48 each last year (crazy deal but under $100 isn’t uncommon)

Not sure about the narrow part but the New Balance Rebel is soft, light, and flexible and can handle a range of paces. You could always try the women’s model if the men’s is too wide (I’m assuming a male here since you didn’t specify). Nike shoes are way too narrow for my feet so maybe they offer something for you.

I prefer V2. The perfect shoe for everything. So if you can get those cheaper it’s a no brainer. However, you said flexible… the Speeds are not flexible due to the plate. Not as rigid as carbon, but still not what we’d call flexible.

I haven't tried the Speed 3, but I have run in the Speed 2 (got to be at least 600k by now and still basically good as new) and the Pro 3 (just 2 runs). The Speed 2s are really quite bouncy and feel great at faster paces but feel a tiny bit awkward at easy pace. They're fairly firm (but still fine for a half) and not super stable but you could probably run in them every day. The Pro 3s are a lot more cushioned and feels much more like a normal shoe. They feel great for long runs and threshold work but I'm not sure if I'd enjoy them as much as the Speed 2s on something like 8x400m. I've also heard they're not as durable and the Speed 3s might be similar.

Never pay full price for a pair of shoes (unless you went to a store and got on a treadmill to get fitted, in which case I think it's fair to buy one pair from the store in return for the fitting). I got the Pro 3s for £126 by searching around. My original pair of Speed 2s were £100 and you can still find them for that price if you look hard. If your shoe size is extreme you can often find them for £80 which is a no-brainer price imo. If your feet are narrow you could consider a womens size if it's cheaper.

If it were my money I'd try to snag a pair of Speed 2s while you can

I wouldn't get the Endorphins, get the higher quality Testosterones.

100%

I realized yesterday that the Speed 3 might be the most favorite shoe I've had in 40 years of running. I'm a little slower than you, but also use one shoe for everything. It's to the point now where I won't wear any of the other shoes in my rotation because the Speed 3 is so right on the mark. (I started with v2, still have a pair of v2, and recently got the v3) I highly encourage you to give them a try.

Also, wanted to second what others have said about grabbing a cheaper pair of the v2. I think the Speed 3 is better (at least I prefer them) but the Speed 2 was/is a great shoe and can often be found for half of its as-new price because the Speed 3. Speed 2 is an absolute steal at anything under $100 US.

I love them for fast long runs. 90% MP. Not quite fast enough to justify wearing my next% but too fast for my regular trainers. They’re great for giving you that little bit of extra pop.

This is my experience. I ran in them tonight on a normal training run and it felt so much faster than my Invincible 2s (Nike). I like both shoes but the Endorphins just "pop" so nicely and aren't as costly or fragile as the VaporFly Next% that I use for real racing.

Running Warehouse had the Endorphins on sale and I got a nice pair for like $98.

I hadn't read your post when I wrote mine... it looks like I plagiarized you!
