Confidence
95/100
“Fit quite long and wide—size down half a size.”
“Laces are absolute garbage; come undone during runs.”
“Forces you up onto your toes, helping increase cadence and decrease overstriding.”
“Runs about ½ size bigger than Saucony and Nike.”
“Lasted only 200 miles before sides separated from base.”
“Outsole is grippy and looks new after 100km.”
“Needs about 30 miles to break in; feels overly firm before that.”

“Upper is race-like and lacks comfort for longer runs.”

A fantastic do it all shoe. Only minor criticism is the weak heal counter.

40 mpw training for a marathon came from the New Balance FuelCell Rebel v3
4/5
Overall
Great shoe and probably the most durable shoe I’ve ever owned which is nice because I tend to over supinate and put a lot of wear on my shoes quickly. I also have rather wide feet so I ordered the wide version and found that it works very well. The cushioning is soft enough for easy to mod distance long distance days, I probably wouldn’t take it faster than 6:00min mile pace to be honest.

Just bought a second pair as back-up as I liked the first ones so much

40 mpw training for 5K and 10K came from the HOKA Bondi 7
3/5
Overall
The ride is awesome. Feels good at steady marathon pace and is easy to handle various speeds. The outsole is grippy and looks completely new after 100km.
*HOWEVER *
The upper feels like a plastic bottle that cuts into your ankle and it’s extremely uncomfortable and nearly impossible to get a decent fit.
The laces are absolute garbage and have been undone during runs and workouts on multiple occasions.
The tongue is flimsy and is not secured properly.
I would stay away from adidas personally because their upper is just not good.

40 mpw training for a marathon came from the Saucony Endorphin Speed 2
4/5
Overall
From first wear, this shoe was comfortable yet snappy. Runs about ½ size bigger than Saucony and Nike. The toe box was perfect, but I do have wider feet. The only complaint is the tongue wrinkles, so you need to make sure there is no folding over, or it could cause discomfort.
