This is the Tyr Maverick, and it promises a foam that makes you faster by increasing your air time between strides. But is this just a marketing gimmick? Or can this shoe actually deliver. It’s time to lace up the Tyr Maverick and take it for a run. 0:00 intro disclosures specs what's it like tyr explained buying guide vs Saucony Endorphin Trainer vs Mizuno Neo Vista 2 Disclosures: this is a pair of shoes provided to me for the purpose of review, so I did not have to pay for them.

The next frontier in the super shoe wars is weight, and ASICS has just unleashed its latest flagship. And at just 4.5oz, it’s one of the lightest shoes I’ve ever tested. This is the Metaspeed Ray, and it’s time to take it for a run. 0:00 intro 0:44 Disclsoures 1:20 Specs 3:40 What’s It Like 7:02 Metaspeed Family Explained 12:23 Buying Guide 13:00 vs Adidas Adios Pro Evo 1 and 2 15:12 vs Puma Fast R3 disclosures: ASICS sent me these shoes to review, so I did not have to pay for them.

I was also recently embedded with ASICS as I covered the World Championships Marathons in September 2025. My travel and accommodations to attend those events were also hosted by ASICS.

Run with me in the Tyr Maverick. They’re using a supercritical foam, Flight Time, that promises more airtime with each stride and fewer steps required per mile. I haven’t looked too deep into that specific claim, but the foam is lightweight, airy, and bouncy. The shoe has a pleasant squish but couples it with a very fast response for an experience that is lovely yet cushioned. This run was a recovery run, and the shoe was pleasant. A subsequent run was an easy run and I definitely found myself inadvertently picking up the pace a bit. Further testing will be to easy if the shoe has long run potential. The shoe it foot shaped with a wide toe box. It almost feels too big for me. But it’s a large shoe with a light weight, thanks to the materials chosen for the upper and that light Flight Time foam. .

Adidas Takumi Sen 11 (and a mini Adios 9 review)
This is not the most popular shoe in the Adidas lineup, but it’s perennially one of my favorite shoes that Adidas makes. This is the Takumi Sen 11, and this year, it’s a case of - the more things change the more things stay the same. 0:00 intro 0:48 disclosures 1:19 specs 3:09 What's It Like 7:37 Adios 9 Mini Review 10:29 Takumi silo 12:07 Buying Guide 13:19 vs Streakfly 2 14:42 vs Cielo Road disclosures: I don’t remember how this shoe got to me. I want to say that I bought these shoes myself, but I can’t find any record of it in my email, so they must have been sent to me. However, regardless of how a shoe ends up on my desk, no one is paying me to make this video or to include their brand in this video.

This is the Adidas Prime X3 Strung. It’s got two layers of carbon, a super tall stack height of 50mm, and upper created by a robot that carefully places each strand of high tensile fiber. But is this shoe a pinnacle of Adidas technology? Or is it just a headline grabbing gimmick? It’s time to lace up the Prime X3 Strung and take it for a run. 0:00 intro 0:58 disclosures 1:16 specs 6:38 what's it like 11:49 Prime X history 19:40 buying guide 21:02 vs Puma Fast RB 22:27 vs Brooks Hyperion Max 3 disclosures: I bought these shoes with my own money.

Men’s Marathon Tokyo World Championships
Today was the men’s turn to run the World Championships marathon course in Tokyo, and the men got similarly sinister condotions. The pack set out cautiously, with a giant pack sticking together for about 35k of this race. But by 40k, things had splintered apart (although there was still a sizable pack going after the podium through the last aid station). @_clayton_young_ fought hard for 9th overall and top American @reedfisch ran a disciplined race, finishing as second American and 28th overall. I haven’t done the math, but from what I saw on the course, it felt like he clawed his way up a lot of spots in the back half of the race. @cjalbertson started off strong and was in the second American spot for much of the race when I was him. But by 40k, it looks like the heat on this very humid day may have bested him. But it was honest effort on the day.

World Championships Marathon Tokyo 2025
This race was moved to start 30 minutes earlier, but the heat and humidity were still oppressive out on the course today. Kobayashi took out the race fast, with the three Americans following close behind. By the 18k mark (it might have been earlier but I next saw the runners at 18k), @susannasullivan4 had taken the lead and continued to run well solo when I saw the runners again at 22k. It was a bit of a surprise to me to see her alone in front, but I was hoping that her last success in the heat meant that maybe she’s just built for this (she finished top American at Worlds in Budapest where the sun and heat were hotter although it was less humid). @jesstonn followed closely behind in third at 18/22k, and because Jess McClain has also performed well in high stakes, high heat races, I was starting to hope that maybe the US could bring in two podium spots. @imtinyrik came through the 18k mark a bit after the chase pack, but seemed to have found a small pack of runners to work with. The last time I saw the runners was at about 40k. Tigst Assefa and Peres Jepchirchir were running stride for stride and shoulder to shoulder. Shortly behind them was Julia Paternain, who secured 3rd place and Uruguays first ever world championship medal in what apparently was only her second time running the distance. Jess McClain finished 4th, looking strong as she came down the final hill into the last kilometer of the race. Erika Kemp came in as the final American on what was a challenging race day.

Sydney Marathon Guide (travel and race week advice from a guy who ran it once)
I just got back from running the Sydney Marathon for my seventh world marathon major star, and this is my Sydney Marathon Guide 0:00 intro 0:43 where to stay 1:51 Sydney airport 3:52 packing list 5:33 food 7:02 things to do 8:36 where to run 9:42 expo 12:21 race morning 18:29 course overview 20:44 0k-5k 21:57 5k-10k 22:54 10k-15k 23:37 15k-20k 24:36 20k-25k 26:19 25k-30k 27:34 30k-35k 28:53 35k-40k 30:27 40k-finish 33:11 reuniting with family Disclaimer: I’ve been to Sydney once. Disclosure: No one is paying me to make this video or to include their brand in this video. However, Sports Tours was my travel sponsor for this trip, and they were the tour group that I used both for lodging and for securing my race bib. I didn't mention the name of the tour group in this video, but their logo did show up on the screen at a couple of instances during some b roll, so I make the disclosure. https://www.abf.gov.au/entering-and-leaving-australia/can-you-bring-it-in/categories/food Thanks for watching!
