6’2 97 to 100kg. I have loved the endorphin series the best. Have exclusively worn since the 2s. Loved them. Hated the 3s. Now on 4s and after trying different shoes, even the pro 2s and pro 3 I come back to endorphin speed 4s. (Haven’t tried 5s yet and will try azuras soon as daily). But have been wearing the 4s for pretty much every run. Will probably get pro 5 as I begin working below 3:45 min/k as base block ends

My most recent race shoe purchase is the AP4. Haven’t run a full in them yet, but have done some shorter races. Previously, I’ve raced halfs and fulls in the Clifton 8, Vaporfly 2, Alphafly 1, Endorphin Speed 2, Adios Pro 3, Zegama 1, Topo Specter 1, Endorphin Trail, Endorphin Pro 3, Endorphin Speed 3, and Tyr Valkyrie Speedworks. AP3 has been my favorite of those. Ran 2 halfs and 2 fulls in them plus an ultra and then put a lot of miles in them as a daily trainer. Great shoe. AF1 was great too, but I did a lot more daily miles than races in those.

I had a pair of Nike Alphafly NEXT% that lasted 880 miles. That version of ZoomX was fantastic. I actually wore through the outsole and the air pod in one of them burst (right in the middle of a 14 miler), but the foam still felt great. For shoes that are actually available now, I’ve had a good experience with several iterations of the Saucony Endorphin Speed. The foam feels good through 500+ miles and the upper and outsole hold up well. They are also good for any distance or pace.

I am not a three shoe rotation but I love the approach here mostly because it reassures me about my choices so far I use Nike Vomero Plus for daily training and especially long runs My old Saucony Endorphin Speed 3’s (not badly used at this point) for tempo and 5k races Can anyone say if the Saucony Endorphin Speed 5’s are a notable upgrade from the Speed 3? I would get them if and when my spouse green-lights raiding the family checkbook.

Great question. Running my first marathon in March and trying to figure this out for my self. 60, 163 lbs (74 kg), 13:00 min/mile pace - so super slow. I have a love hate relationship with SB2s. At my current paces they are clunky blocks of foam. While I can roll off the toes, activating the foam through my forefoot takes a lot of effort which becomes harder as I get tired. I know I need to strength train more. And the shoes are more alive around 11 min/mile and faster. But I ran my half marathon earlier this month in Endorphin Speed 3s even though I primarily trained in the SB2s. They’re just not working for me. The Speeds just felt lighter and had more pop. I am able to run 30 seconds faster per mile on average. So same question - what are the best shoes for a slower runner for a 5-6 hour marathon.

Personally I wouldn't be using the endorphin speed 4 for a marathon. Speed 3 and 2 were great and would have used them but the 4 just felt harsh under foot. Probably more a Personally thing. Superblasts would be my first pick for unplated that I would run a marathon in. Stable base and the shoe just works perfectly for me doing about 5min ks. Evo SL are a maybe but I honestly haven't taken them more than 20k in one run. They felt great up till then but until I take a shoe over 30ks its an unknown for me
