Just read the article. Mid sole is combination of Eva and tpe-a foam. Eva is just normal foam, don't know about tpe-a. QD and Adidas pro 3 uses tpee, don't know how similar it is to tpe-a.
But with Eva there, don't jump yet, I think wait for more reviews.

**Differences Between TPE-E and TPE-A Foam**

1. **Chemical Structure**:
- **TPE-E (Thermoplastic Polyester Elastomer)**: Derived from polyester (e.g., polybutylene terephthalate) and polyether/polyester soft segments. Common trade names include Hytrel®.
- **TPE-A (Thermoplastic Polyamide Elastomer)**: Based on polyamide (nylon) hard segments and polyether soft segments. Known as PEBA (Polyether Block Amide), with trade names like Pebax®.

2. **Temperature Resistance**:
- **TPE-E**: Moderate heat resistance (typically up to 150°C). Suitable for applications requiring durability at moderate temperatures.
- **TPE-A**: Superior high-temperature performance (up to 170°C) and better low-temperature flexibility (down to -40°C), ideal for extreme environments.

3. **Chemical & Environmental Resistance**:
- **TPE-E**: Excellent resistance to oils, fuels, and solvents. Susceptible to hydrolysis in moist, high-temperature conditions.
- **TPE-A**: Better hydrolysis resistance and UV stability. Moderate chemical resistance compared to TPE-E.

4. **Mechanical Properties**:
- **TPE-E**: High tensile strength, stiffness, and creep resistance. Good abrasion resistance.
- **TPE-A**: Superior elasticity, fatigue resistance, and lightweight feel. Excellent impact resistance and flexibility across temperatures.

5. **Applications**:
- **TPE-E**: Automotive components (seals, hoses), industrial belts, and electrical connectors due to chemical resilience.
- **TPE-A**: Sports gear (ski boots, shoe soles), medical devices (catheters), and wearables requiring flexibility and biocompatibility.

6. **Processing**:
- Both use injection molding and extrusion. TPE-A often requires higher processing temperatures due to polyamide’s higher melt point.

7. **Cost**:
- **TPE-A**: Generally more expensive due to polyamide content and specialized performance.
- **TPE-E**: More cost-effective for applications needing chemical resistance without extreme thermal demands.

**Summary**: TPE-E excels in chemical resistance and mechanical strength, while TPE-A offers superior temperature range flexibility and hydrolysis resistance. Choice depends on application-specific needs for temperature, environment, and mechanical stress.

Too firm lah, forget it. Just stick to china shoes if your budget is like that.

BTW you guys remember that Decathlon Kiprun 900?

Also too damn firm, for me is literally i think i cant even run in it for 3k.

Pro vs amateur


That last pro (young also) 400m 69s is bloody slow, totally cannot be ......very obvious he held back for the photo finish.

 

[WussRedXLi]

Oh Joshua Cheptegi got run.
2:05:59

Ok lah, at least PR again after his first debut at Valencia (2:08 i think)
And looks stronger too (he needed to be assisted carried away @ Valencia then think lower half mabok liao)

I finished Tokyo Marathon and set new PB of 4:31.

Overall an enjoyable marathon to run. The route took the runners through major streets in Tokyo. Could use a bit more variations in scenery though like maybe running through one of the larger parks. The vibe was good.

Temperature was warmer than the Hongkong one I ran last month. Water stations were spaced too far apart and chaotic. Combined with the heat I think it was rather brutal to overseas runners from colder countries. Many angmors were limping and red like crabs.

Runners seem to be very international. Like almost 50% runners I saw were foreigners. Many many chiobus from different countries.

I used a new pair of carbon plated Asics S4+ Yogiri for this marathon. It was a great pair of shoe. It was like Glideride but with lower stack and much more stable.

Well done! I will keep trying to ballot for it

I will ballot for all the other majors also. Hope I can get NYC.

i am thinking of taking creatine to help with my recovery since the strength training has kind of hamper my run training. has creatine helped you guys so far?

Can try this........

BTW, the second vid the fella was shifting his feet the whole time. Not too bad still can complete but best is if you do not shift your weight around by moving your foot. (some weakness somewhere)
You see how Jeff of Athlean-X in the first vid does it.

I originally thought he this kind of high level cant improve by much liao, really surprising to me

 

[WussRedXLi]

Makarun hooted Tokyo

2:50

He is young, late 20s only.....sure can improve one. If i am already 50s and still improving (damn %!@# slow tho) then i dont see why others cant. In fact iirc he still has not broken 17 mins for his 5k so for sure still got much more to go (probably just that he has not really specifically trained much for that range).

In fact not even sports. Easier to track are stuff like push ups, some cali movements, lateral raises, shrugs, rows, bicep curls etc. Slowly but surely.

But one thing for sure is that when people get older, the risk of diseases/co-morbidities increases. Coz of previous decades of "mistreament" of your body. Vs a 20+ year old, chances are that your body still not that much "mistreated yet". Take for eg BMD...... If lucky, that manisfests as just pain here pain there every now and then, or if buang on the bike then you get fracture more easily and puts you out of action for a few months.
If unlucky, just drop dead.
Recovery also probably slower....... heck some older people after age 40 have difficulty sleeping or falling back to sleep after getting up to pang jio, much less getting that min 7-8 hrs of sleep. Or have enlarged prostates and peeing so many times in a night that every pee also needs 30 mins to fall asleep then terok.
And the issue of muscle loss so gaining muscles / strength is against you.

But these are not insurmountable challenges, can be fixed one.

So if those bumps can be fixed coz you have set your mind to it and willing to fix it , seriously no other limits with regards to improving in your middle age.......
