The thing is, that they were SLOW AS MUD. Seriously, that bad. Like so bad that even though I'm only in my mid-40s, I assumed that I was hitting my big age-related slowdown since my paces at all speeds were off by 30sec/mile, sometimes 40sec/mile.
Is that the only issue with the Bondi? From a training standpoint that’s not much of a problem, as long as you have other shoes for races or speed sessions.
It's actually not the only issue with the Bondi. I also have found that if at least for me, as a triathlete that doesn't run much more than 30 mpw on average, if I use the Bondi for even just half of those miles, I start losing my leg-impact resistance. Which means that the moment I switch to a race shoe, and run even normal distances not at particularly faster paces, my legs start feeling the beatdown. Especially on anything downhill.
It's very similar to someone who only trains exclusively on a soft treadmill and then goes and races on the road with not enough road-specific miles off the treadmill. You'll definitely feel the beatdown, and if it's a longer race, you may drop way off pace as your quads can't take the beating.
I intentionally offset this (successfully) now by making sure I get enough miles not in the Bondi, but also on a long route with a sufficiently steep long downhill so my legs can stay impact-ready for the distances I'm training for.
If you're however running megamiles like marathon-specific training, though, this is less of any issue depending on how many miles you're putting in. At some point, especially over 70mpw, it's more important to preserve the body against injury-impact (but still continue muscular endurance) than to continue overloading it for impact.
I've stopped using the Bondi for my originally intended long runs because I was noticing specifically this weakness as a lower-mileage running triathlete. I use it exclusively for recovery days now, your mileage may vary! (I still use the Saucony Triumph maxi shoes for long run - they aren't speedy either, but I get a bit more road impact, enough not to hurt my arthritic joints, but still get enough leg beatdown.)
