I was recently invited to join a run from the ASICS Regent St store to celebrate the 25th Anniversary and launch of the new Gel-Kayano 25.

Early morning 40-odd runners came together to run a route from Regent St to Hyde Park where we would doing a stability circuit before a run past the Serpentine back to the store for refuelling and chats.

I was lucky enough to be one of the first people to try out the new Gel-Kayano 25’s, delighted that the store had pairs in Size 14’s and 15’s which I find is a rarity.

I got the beautiful Black pair, the look of the shoe is fantastic no matter what the colour and it’s one of the favourites of my ever growing shoe collection.

I’ve had the opportunity to wear them for about four weeks now and I really like the shoe a lot. I’ll go into more detail below but they really suit my running style and where I like to run – good for both road and dry trail.

Here is what ASICS say about the shoe along with some stats:

“Almost everything about this shoe is focused on endurance, with its medial support system, metaclutch for improved levels of heel-holding and FlyteFoam Lyte technology all included to ensure that the wearer has the support needed to reach a new level of performance.

Comfort is also king with the GEL-KAYANO 25, with FlyteFoam Propel offering an improved level of bounce and both the redesigned jacquard mesh and spacious toe box ensuring that your feet will remain in a top condition no matter how many miles you plan to tackle. The shoe’s Ortholite X-40 sockliner is another key feature which offers the twin benefits of performance and comfort.”

  • Weight 336g
  • 10mm heel drop
  • Jacquard mesh for enhanced fitting
  • Metaclutch for better heel-holding
  • Flytefoam Propel
  • Flytefoam Lyte
  • Medial support system
  • Spacious toebox
  • Rearfoot visible gel
  • Non-visible forefoot twist gel
  • Ortholite X-40 sockliner


The K25 has a breathable mesh structure around the top of the shoe which hugs the foot and conforms to the shape of your foot.

I find that compared to the Kayano 24 the heel it much more of a secure fit, thanks to the additional padding, one of the reasons I didn’t find myself running in the Kayano 24’s that much and used them as an occasional shoe instead.

Even though the mesh is there to hug the foot, I haven’t been required to change the lacing to make the toe box fit. I tend to have particularly wide feet and previously used to lace my shoes differently to accommodate them – not required in the Kayano (FYI: these are the standard fit, not wide fitting).


The mid-sole is something to behold, there are so many parts to it, all with the aim of helping to food transition naturally and smoothly. The most obvious piece on the mid-sole is the Guidance Line and Guidance Trusstic System, this crossed from the heel to the forefoot. This helps keep the shoe stable and prevents the shoe from twisting when under stress.


The outsole of the shoe is grippy but not overly so. I’ve used the shoe on both road and trail. On the road it’s responsive and offers good return of energy and is comfortable. I headed to Parkrun on Wimbledon Common last week and decided to take the Kayano  25 to the nice dry compacted trails. Obviously there was less of a bounce from the shoe, but they were still comfortable and handled the tricky trails with tree roots and uneven surfaces exceptionally well. My only complaint is the state of them afterwards, the black really shoes us the dusty nature of the course post run.



My favourite shoe is the ASICS Gel-Nimbus 20’s, in fact I love them so much I’ve bought my own pairs since receiving the Nimbus London Edition in March. The Nimbus are a neutral shoe, whereas the Kayano are for stability, so a direct comparison isn’t fair and unnecessary as depending whether you’re a neutral or over-pronator you will select the one for you.

However in terms of comfort the Kayano really do give the Nimbus a run for their money in terms of my favourite. They are a very stable and inflexible shoe, you can feel this whilst running


I hate to admit it, but yes I like pretty shoes. This doesn’t drive my absolute decision making but it is certainly up there. The Kayano 25 fit the bill, I received the Black version of the shoe and that would’ve been my colour of choice, despite the fact they look really dusty after a trail run.


The fit is true to size. I wear UK 14 / US 15 in all of my ASICS shoes and this is no different. As mentioned I prefer the fit of the Kayano 25 compared to the 24’s with the cushioning and locking system around the heel.


336g sounds like nothing but in a world of Hoka Clifton’s and On Cloudflow they do come up a little heavier and hand-in-hand you can tell. However wearing them I hardly noticed much difference between this and the Nimbus 20’s which are my usual go to shoe.

The additional weight isn’t wasted with unnecessary pieces and is worth it for the stability and comfort it offers.


A premium Stability shoe that works well on road and dry trail.

They fit is extremely comfortable, there is no heel slip for me and it’s a sturdy shoe without being uncomfortably inflexible.

I am primarily going to use this as a training shoe and keep to my Nimbus 20’s as my racing shoe given they are a little lighter and work better with how I run.



I did receive the shoes from ASICS no charge, this did not influence my review of the shoe.
