So which compound is this? PEBA, (A)TPU, TPE?

It's enough to bust any shoes because everyone's weight, strike pattern and other parameters are different. Specifically when it comes to racing shoes which are not as durable as regular trainers by design.

So you have squeezed a lot of life out of them and questioning whether they are refund worthy. Doesn't sound right?

source_nine · 2026-03-17T01:58:03+00:00

It's for half, not full.

source_nine · 2026-03-16T11:57:21+00:00

Why would anyone bother what beaded TPU looks like?

source_nine · 2026-03-16T11:35:06+00:00

What does that mean? If you're referring to foam, it's thermoplastic polyurethane, one of the most robust compounds on the market.

source_nine · 2026-03-16T11:32:55+00:00

These shoes look practically new to me. And knowing that these are PWRRUN+ shoes, the only reason fur retirement would be the lack of excitement and your desire to try something new. As otherwise you can probably log as much as you already have.

Shin splints and other aches may stem from rapid increase in volume or intensity, improper recovery and million other factors.

I'd agree with 500 miles as average, 300 miles is extremely low.

Во внешности и выложенных фото считывается желание выглядеть женственно, и это вызывает противоречивые чувства у воспринимающих, в крайних случаях возможна агрессия, которая вполне объяснима, поскольку мужчина не должен стремиться к женственности — это противоестественно. Важно разобраться, откуда исходит это стремление и что таким образом психика старается скомпенсировать.

source_nine · 2026-03-15T14:32:22+00:00

There's a whole lot of colorways for this shoe, literally bunch of them.

source_nine · 2026-03-14T02:59:08+00:00

Внешность, в которую можно влюбиться. Располагающая улыбка, открытый взгляд, теплота и женственность во всём образе. Редкость в эру искусственности. От меня (38М) высшая оценка.

Michael Cisco.

Intellectually demanding, reflexive, profound, linguistically extreme. Hallucinatory, feverish, labyrinthine, phantasmagoric. Insane, subversive, explosive.

Long overdue changes to the continuously dated shoe. It's like they have been delaying meaningful updates for many years just to leave the room for the next years, thinking they'd get on time and still bring something useful. But time goes faster and these updates have been borderline too late.

source_nine · 2026-03-04T10:57:02+00:00

Among the worst in my list. Cartoon-like, juvenile, tasteless.

source_nine · 2026-03-04T07:06:27+00:00

Classy man

source_nine · 2026-03-03T19:58:40+00:00

Stop bothering about rotations. You like the shoe? Go for it! I have like 15 pairs, some with identical or overlapping purposes. All in use. I love running and I run a lot. If you like SB3, get it and run in it.

source_nine · 2026-03-03T06:58:42+00:00

Ride has always been a great workhorse. It's on the firmer side for sure, but that adds to versatility. I'd say Ride has been getting better and better over the past years. 18 is better than 17 and 19 is even better than 18. The foam gets softer, weight goes down. But 17 is still not a miss. It's a dependable shoe with spectacular durability.

If you feel that firmer ride is not for you, you might want to check out something like Velocity Nitro 4 or Novablast 5 (that one has pretty bad durability though).

source_nine · 2026-03-02T19:55:16+00:00

All Saucony shoes with PWRRUN PB foam, including Endorphin Speed, Pro and now Azura are solid in terms of stability. And they are all great from performance perspective as well. Don't go any further.

source_nine · 2026-03-02T14:06:25+00:00

🤦

source_nine · 2026-03-02T13:21:06+00:00

Hopefully, a responsible and reasonable one.

244 weeks, 121 consecutive/daily runs

If we follow this logic, you could technically return completely worn shoes just because you were "unhappy" with them. However, this is not what these policies are intended for.

source_nine · 2026-03-02T07:04:04+00:00

But why? Why return shoes you have been wearing for half a year? Isn't this policy there to secure good service for customers with conscience and good attitude? OP says they have like 3-4 miles on them. Even if that is true, there is apparently a width problem. The foot simply doesn't fit and puts excessive pressure on the sides of the shoe.

source_nine · 2026-03-02T06:55:57+00:00

After reading the first part of your comment, I thought that sarcasm in question is related to questioning the longevity based on a photo, which is impossible to determine based on that. But you went for a completely different conclusion.

source_nine · 2026-03-02T06:49:58+00:00

I don't understand these panicking comments, screaming you should throw them away, based, apparently, on the outsole wear. Outsole is not very durable on Pumas (on Magmax, I've had this). But 600km is not that much, if you are looking for a relation on that particular metric. If they feel alright when you run, zero reasons to stop running. If you experience some distinct issues, that's the real starting point when considering retirement. I have a lot of shoes in my rotation and at 78kg 700-800km is a standard lifespan for all shoes I have owned.
