New Balance FuelCell SuperComp Elite v4

“Initial impressions of the Adidas Adios Pro 4 (US M9) 36M, 5K - 18:30, M - 3:08 5'11, 135lbs Midfoot striker, run 50-60 mpw I just picked up the Adios Pro 4 as I'm looking for a new shoe to run the Boston Marathon in this coming April. Current shoes in my rotation include: New Balance SC Elite v4 (200mi), Nike Vaporfly 3 (100 mi), New Balance SC Trainer v2 (400mi x 2), Hoka Mach X (400 mi), Adidas Evo SL (100 mi), New Balance 1080 v12 (300 mi), New Balance Rebel v3 (200 mi), Nike Streakfly (100 mi). Pictured here are the Adios Pro 4 as well as my pair of Evo SL that I've been using for most of my runs the last few weeks. When I saw that the white colorway for the Adios Pro 4 was finally out I jumped on it, as I had been waiting for this release for a while. I'm looking for a new shoe for Boston where I'm hoping to go sub-3. My previous two marathons were run in the NB SC Elite v4 (3:26 then 3:08) and I also regularly race in the Nike Vaporfly 3 (up to HM distance). Fit: Initial step-in felt great and TTS. Compared to the Evo SL, they are much more snug in the toe box. I was a bit disappointed when I got the Evo SL because at a US 9M I felt like they were a little too roomy and I had wished I would have sized down. I was thinking of getting the Adios Pro 4 in an 8.5 but I read online that they are a bit shorter and narrower, so I went with my standard 9 and I'm glad I did. The upper feels fantastic and very similar to the Evo SL but a bit more structured. The gusseted tongue is a welcome addition and there is some additional structure throughout the ankle collar and heel cup, which is a nice improvement. The drop feels fairly minimal and you can immediately tell there is a huge slab of Lightstrike Pro under your midfoot. Rubber on the bottom is super grippy. Run: I ran a quick Progression run from recovery pace to MP over 6 miles on my treadmill tonight. My legs are pretty dead from an LT workout yesterday, but I couldn't resist picking up the pace a bit and testing these out at MP. At slow paces, around 8-9 min/mile they feel pretty unstable and very soft. You can feel the huge slab of Lightstrike Pro underfoot, which is very soft. One thing I liked is that they felt like a fairly neutral footstrike. In the Evo SL, I feel like they have a tend to roll your foot a bit and induce some pronation, which is uncomfortable for me as a slight supinator. No sense of this at all with the Adios Pro 4. As I began to pick up the pace a little they really started to come into their own. Around 7:30/mile pace I really felt them turning over. They are very lightweight and Lightstrike midfoot is a dream. With the aggressive rocker I felt like they just flowed from stride to stride. One thing I noticed is that I tended to have a pretty aggressive toe-off and my actual turnover was somewhat slow, I was only hitting a cadence of 170 or so when I expected it to be a bit closer to 175 for the effort I was putting in. As I picked up the pace the”
