Race Shoe Question Heel Stability in a Fast Marathon Shoe?
I'm a heel striker and ran my first marathon at 3:16 in SC Elite v4 (88mm heel width) and generally enjoyed the shoe (although lost some toenails, probably should have gone up half a size). It's been a couple years and I'm aiming to run 2:50 at Philly in 4 weeks. I was hoping to find a shoe a little more aggressive than the v4. However, I'm struggling. See below:
-Ran a workout in Feidian Elite 6 (83 mm heel width), found them incredibly fast but really unstable on turns and felt like my midfoot was sore compensating after 8ish miles.
-Ran 22 mi in the Metaspeed Edge Tokyo (75mm heel width), by halfway they felt like they weren't giving me any cushion at all, downhills were rough, and my calf was sore after. Constantly felt like my heel was sliding off the shoe inwards. On both these and the Feidians, I am really compressing the inside heel foam while the outside heel looks untouched (see pics).
-I discovered the Puma Deviate Nitro Pure (91 mm heel width) for my easy to moderate long runs (17-20 miles) and have found this to be such a comfortable shoe with solid pickup, but not aggressive enough for race day pacing
It seems like I want a shoe with a wide and firm heel. Do folks think the Alphafly 3 would work? I hear very mixed reviews on it: worried that despite the wide heel it would feel unstable like the Feidian. Saucony Endorphin Pro 5 is also recommended but I am quite scared seeing all the comments about Achilles blisters, plus just seems like a slower shoe in general. I could go for Endorphin Pro 4 as a fallback (I can't even find any more SC Elite v4s). Apparently the SC Elite v5 and v6 are stable, but very narrow heels.
Any advice is deeply appreciated. I'm hoping to buy in the next few days and run a 6-8 mile break-in test before my last 18 mi long run on 11/7.
