The Yonex Power Cushion Fusion Rev 4 is the NEWEST Yonex tennis shoe for 2021 which is focused on durability and comfort. But will the newest tennis shoe of 2021 it hold up in the signature tennis shoe performance review featuring the playtest, serve test, durability test, teardown and suicide test?

As a foot doctor I look at tennis shoes and tennis shoe technology a bit differently as I focus more on what foot types benefit from these shoes as well as the tennis shoe’s functional attributes on the tennis court

Some of the main areas we cover in this tennis shoe playtest, and performance review of the Yonex Power Cushion Fusion Rev 4  are:

– The weight, durability, fit and playability
– What are the features of the insole, midsole, and outsole
– Yone tennis shoe technology explained

    Thanks doc. Could the ankle be locked down easily by the lacing system?



  2. Sören Lührs on August 14, 2021 at 9:51 pm

    Could you rewiev the head sprint 3.0’s?



  3. Steven howie on August 14, 2021 at 9:51 pm

    What brand or type of tennis shoes have the most bare foot feel e.g minimal heel drop



  4. Brett S on August 14, 2021 at 9:51 pm

    Could you do a review and teardown of the Dunlop Activector tennis shoes?



  5. Mason Wrisley on August 14, 2021 at 9:54 pm

    I am between two options now to replace my ubersonic fours, I want something minimal and that will last a decent while, I was wondering your thoughts between the ubersonic 2s, which I love, or the lotto mirage 100s which I don’t know much about



  6. LS Fire on August 14, 2021 at 9:54 pm

    But can you hardcourt slide in these shoes????



  7. Alan Shum on August 14, 2021 at 9:55 pm

    Any plans for nb 996 review?



  8. Serkan Ozbay on August 14, 2021 at 9:56 pm

    What specialty of a shoe makes it better for tendonitis? Which Nike tennis shoe is best for tendonitis? Thanks!



  9. Qiller on August 14, 2021 at 9:57 pm

    YES! the review I have been asking for! Great content! A question though: I have achilles tendonitis, would you suggest rev 4 or nike gp turbo?



  10. Sajith Gopinath on August 14, 2021 at 9:57 pm

    Hello Foot Doc, could you suggest a good trainer for badminton which costs at 50 to 60 USD. I’m suffering from sciatic pain and my right heel is in pain almost everyday. I’m from India so could you make a suggestion?



  11. Yuanming Song on August 14, 2021 at 9:59 pm

    Decathlon also make some tennis shoes, and they’re super affordable like everything else they sell. Any plan on reviewing them (their tennis rackets & shirts are great)



  12. pipe12435 on August 14, 2021 at 10:00 pm

    Any opinions on wilson shoes would love to see a review on kaos or rush pro shoess 🙂



  13. jim blankenfeld on August 14, 2021 at 10:04 pm

    Awesome review – again – Zach, and thank you for including Pickleball in your review! When a new court shoe comes out, I will definitely watch your tear down/ review.



  14. bluedragonvn on August 14, 2021 at 10:05 pm

    Can you do a review of the Yonex Sonicage 2? They seem decent but being the lowest tier at $105 doesn’t really compete well with other low end models from other brands that you recommended for under $100 shoes.



  15. shane travis on August 14, 2021 at 10:06 pm

    This is a tennis focused shoe review channel. But I’m just looking through to find the most durable shoe for outdoor basketball 🤣. Thanks for these reviews I really enjoy them.



  16. vladimir vladi on August 14, 2021 at 10:07 pm

    Hey Doc! Can you do a comparison video of “heavyweight” shoes like : solarboost vs court ff vs cage 4 vs eclipsion ‘21 and such? And one of lightweight: air zoom vapor vs solution speed vs ubersonic and such?
    Thanks a lot



  17. Santiago Bergallo on August 14, 2021 at 10:08 pm

    I loved the video! But with my blisters problem and my tendency to slide to get some forehands, if I were able to choose I think I would get a more beafy shoe. Sadly here in Argentina we tend to buy whatever we find when we find our size.



  18. Rel on August 14, 2021 at 10:09 pm

    I see you have gone back to old faithful RF97, my favourite racket but due to a shoulder injury it is one I can no longer swing. Any plans to test new rackets such as the Vcore 95?



  19. Víctor Lagos on August 14, 2021 at 10:10 pm

    Hey Doc. How this compare to the previous FusionRev 2?



  20. Paul Kwan on August 14, 2021 at 10:12 pm

    how is it compared to asics speed ff 2? thanks



  21. Marcel S on August 14, 2021 at 10:13 pm

    The Fusionrev 4 run quite long, but even in an appropriate size (lengthwise) they have too much volume in the toe box for my narrow feet at least. In consequence, the upper polyurethane on the toe box folds when stepping forward creating an uncomfortable cut. For that, they are not for me unfortunately.



  22. Villiam Stranf on August 14, 2021 at 10:16 pm

    Do you know if new PC Eclipsion 4 is coming?
    Btw what would you like more Diadora Blueshield or this Yonex?



  23. Soham Datta on August 14, 2021 at 10:16 pm

    I just want to let you know how insanely grateful I am and how much I love you for your videos. I had been having tons of arch pains when playing tennis and it was getting so bad that I was considering quitting my tennis season in school . But after watching your video on best insoles, I got the Powerstep Pinnacle and it literally saved my life. Its been about 3 weeks since I bought it and I barely feel any pain when running and playing with these insoles. It helped a l out financially as well as I didn’t need to buy a custom 600 dollar insole. Again thank you so so so so much. 😀😀😃😃



  24. Chhana Ralte on August 14, 2021 at 10:17 pm

    Power cashion or normal



  25. vivek allu on August 14, 2021 at 10:18 pm

    Amazing content Zach, l have a very slim lightweight frame 130 pounds and narrow feet. I want to slide on hard courts and l like light weight shoes. Which ones do you recommend? I don’t care about durability, l can change every 2 months. I want to feel the ground with my toes, drag toes and slide laterally



  26. Owen Rivard on August 14, 2021 at 10:18 pm

    Yonex shoes so underrated but coming from the badminton world I knew to check em out 🔥



  27. J Ray on August 14, 2021 at 10:24 pm

    How does it compare to Ubersonic 2?



  28. onlydoodle12 on August 14, 2021 at 10:27 pm

    Hey doc thanks for the Pickleball love!!!



  29. Muslim pure recipe on August 14, 2021 at 10:29 pm

    🙆‍♂️



  30. Geau Sport on August 14, 2021 at 10:29 pm

    Thanks for the mention of the Geau Sport Axiom Tennis bag Zach!



  31. Paul Musarra on August 14, 2021 at 10:34 pm

    Great job as always Foot Doc. Question for you. I have a narrow heel and a low volume foot so right now I’m wearing the head Sprint SF and they work well but the shoe has changed in the newest version. Any other suggestions ? For additional perspective, shoes like the Gel Resolution 8 are a terrible fit for me. Thank you as always.



  32. BiLaL Tennis on August 14, 2021 at 10:35 pm

    Would love to have known the fit for the Adidas SoleCourt Boost the same way you’ve done in this video. Awesome stuff and I’ve subbed!



  33. Joseph Dente on August 14, 2021 at 10:35 pm

    Thanks for the in-depth review – always come to your channel for shoe reviews 🙂



  34. Felipe Apolinario on August 14, 2021 at 10:36 pm

    Hey Zach, which pair of shoes do you recommend for cushioning and breatheability (for tropical weather) at the same time? I currently jump back and forth from vapors X, which is better in heat exchange but offer a minimalist cushioning, and court FFs, which offers great cushioning but heat the hell out of my foot! After a 3 hours match using the vapors, I feel lots of pain in the ball of my feet, and using court FFs I feel like I am with my feet stuck in mud lol



  35. Jose P on August 14, 2021 at 10:38 pm

    My shoes always rip at the big toe section of the outsole, probably due to my aggressive baseline play. Any shoes you recommend with really strong durability, especially on the outsole?



  36. Garret on August 14, 2021 at 10:38 pm

    Excellent review; I 100% agree! Great looking shoe, but when I tried them on they felt okay with the exception of that super wide slipper tongue. I felt like I had to really tie them down super tight just to not slip out. My biggest concern was that I’d slip when cutting. I ended up choosing the Nike Vapor Pros thanks to your review! Very fast, very quick, very nice shoe

    Love your SCC shirt! Go Artichokes!!



  39. Mason Wrisley on August 14, 2021 at 10:47 pm

    Another good video doc, are you still working on that comparison video between the stycon and the next level



  40. MrCopilt99 on August 14, 2021 at 10:47 pm

    I’ve been waiting for a long time to see someone do a shoe review on these. Thanks a bunch!



  41. Jin Jin on August 14, 2021 at 10:48 pm

    Babolat Jet Mach 3 has arrived. did you get it and will you be testing it soon ? Jet mach 2 had some great reviews in previous video



  42. DEE on August 14, 2021 at 10:48 pm

    I HAVE A REQUEST.. I trust your shoe reviews so much. And since you are a foot doctor, you have good knowledge of the materials and how they impact the body in motion. CAN YOU PLEASE PLEASE review the NIKE AIR ZOOM GT CUT.
    Its initially a basketball show, but it supposed to keep the foot locked in for lateral movements because it has a TPU stop on the lateral side; so would be helpful with tennis players as well.
    I would love to see a review on it. I believe they are due for a release any day now.

    Appreciate it Doc.
    Keep up the good work.



  43. John John on August 14, 2021 at 10:49 pm

    I really wanted to love this shoes, but it’s killing my foot. Such a high quality shoes tho



  44. J Gads on August 14, 2021 at 10:50 pm

    Diadora Fly 3 a better option than these for a wider, high-arched foot, I assume?
