How much speed increase could one expect from a shoe like the Mach 6 vs. an everyday trainer like the Clifton 9?

Got 3 months to go under 20:00. My last test run in the neighborhood was 20:35 about a month ago so trying to really lock it in and make sure I hit sub 20 at one of my 3 races coming up.

Is it really worth it to have 2 different pairs?

It won't buy you the 12 seconds per mile you need but it's probably good for shaving a few seconds off overall. The good news is that 3 months is plenty of time to knock that down. If you end up buying a pair for racing, use them in some of your speedwork to get a feel for them at race pace.

You should be running in two different shoes anyway.

Try some carbon sole shoes. I don’t know about knocking 30+ seconds off a 5k but will be better than just just reducing a few mm of foam.

I would say get a better shoe that's mean for a race but also something you can use for high speed intervals. For Happy's 5k runs, I'll do 2+ miles in my normal trainers then swap to either my old Alphaflys or my Pegasus Turbos. I have used those for interval training only.

Nike now has the Streakfly which is designed for 5k-10k racing. You don't need the massive amount of cushion and carbon plating that a marathon shoe would use. This shoe does exactly what you need for a 10k road race.

Do something similar and get a daily trainer, a high speed interval trainer, and a race day shoe. I cannot stress enough how much of a difference you'll see in performance and overall leg/foot health you'll experience when you can swap through shoes regularly.

Probably won’t drastically change your times, but part of it is psych anyway. Look fast, feel fast, run fast. Go snag you some carbon plated shoes. 20:30 5k is plenty fast enough to utilize a real race shoe.

try using only one shoe. NCAA cross country championship today this guy lost a shoe half way through the 10k race. he easily went sub 20 for the final 5k

I was hoping someone was going to mention this absolutely insane run by Samuel - don't forget he got 2nd place with only 1 shoe and a bloody foot

In my opinion for a casual runner, the benefit of high end race shoes is the superior comfort, recovery and ultimately enjoyment that comes along with using these high end foams. To me, that's way more important than shaving a few seconds off a PB.

Get the Streakfly if you're doing 5ks.

I have a pair of carbon plated race day shoes that I ONLY WEAR ON RACE DAY.

They are too expensive, and have too short of a shelf life, to use for anything other than races.

It boggles my mind how I see so many runners around here wearing $300 Alphaflys or Adizeros or Metaspeeds for a normal workout, only for me to pass them running at my warm up or recovery paces.

They are worth having for races as they truly do make a difference, but they last only so many miles. They won't fall apart at 100 to 150 miles - my Endorphin Pro 3s from last season are still completely in tact and completely wearable and usable - but they don't have anywhere near the pop or energy return or spring as they had when I first got them.

This season I wore Metaspeed Sky+ for my races - a half marathon, a full marathon, and 3 full Ironmans - thats about 117 miles so far - and I'll wear them for one more 70.3 before I retire them and they become a tempo day shoe. The spring is still there, but not as much as the first mile I wore them. It's not the carbon plate that gets worn out, its the foam. The foam is what truly provides the benefits and it only lasts for so long.

If you want to wear them for normal training runs knock yourself out but just realize that the benefits of them only last about 100 to 150 miles max.

True but I'm not trying to run a million miles. I'm just trying to knock a sub 20 5k off my old man bucket list one time. I'll probably wear them at least one day a week during speed workouts and other than that save them for races.
