One of the pairs I tried post run was the ASICS Superblast 3 running shoe. As someone who was keen to keep my running up after the big event, I wanted a comfortable trainer that I could take on longer sessions, that would support my joints and help me recover without causing any additional stress.The Superblast 3 promised that.Unusually, though, these trainers are actually unisex. This means there's a variety of sizes for both women and men, and everyone gets to choose from the same colours. This is ideal if you're fed up of the pinkwashing of women's trainers but also means they've made a couple of design choices that might not be for everyone.At the Daily Mail, we've reviewed dozens of running trainers, most of which have separate models for women and men. So be sure to also check out our reviews on the Brooks Glycerin 23, Brooks Flex, Altra Experience Flow ST and Nike Vomero, as well as our full guide to the best running trainers. And if you're looking for the full set up, we also have tried and tested features on running headphones, running leggings and even running socks.Otherwise, read on for my full Asics Superblast 3 trainer review below. I was excited to test the Superblast 3 as part of my post-marathon recovery. Asics Superblast 3 trainers: At a glanceAsics Superblast 3 running shoes★★★★★Product SpecsWeight239 gMaterialEngineered woven upper, FF BLAST PLUS cushioning, FF LEAP cushioningWhat we loveWeightSurprisingly light given their sizeCushioned midsoleMeaning a lot less pressure on your knees outdoorsWhat could be betterSizeThe large cushioned sole makes it harder to run on a treadmill, better for outdoor runsMy verdict Compared to some of my previous running shoes, this model features a much larger and more cushioned sole, creating a noticeably bouncy run. Although the shoe itself is lightweight, the oversized design can make it feel slightly bulky at first. However, the extra cushioning helps to reduce the impact on knees and legs during outdoor runs. The Asics Superblast 3 trainers are great for people who want something for everyday outdoor running. I don't recommend them for treadmill runs but for your longer park or city runs these shoes are great - and low impact on your knees, which is a huge plus!Overall I was impressed with the Superblast 3 trainers and liked how low impact they were.How I testedTo properly test the trainers, I used them across a variety of workouts, including long-distance outdoor runs of up to 15km, short sprint and speed sessions on the treadmill and multiple outdoor runs at varying distances and paces. From my experience, these trainers are best suited if you are aiming to improve your pace or achieve a personal best over longer distances.I managed to set new personal bests in both my 5K and 10K while wearing these shoes, which was a huge bonus for me. Initially, during my first wear, I experienced slight discomfort around my feet. However, after the second run, the shoes began to mould more naturally to my feet and became significantly more comfortable. I tested the Superblast on long distance outdoor runs and shorter treadmill workouts.Design and features The overall design of the shoe feels premium, with a thick foam midsole that delivers comfort. The cushioning is especially noticeable during longer runs, where the shoe helps maintain comfort and reduce fatigue on your knees.Size and comfort When purchasing running shoes, it is often recommended to go up by half a size to allow room for foot expansion during runs. Following this advice, I ordered a size 4.5. However, when the shoes arrived, they appeared larger than expected and felt slightly too roomy. I think if ordering these shoes, you should order your normal shoe size. Buy these shoes in your usual size - they are very roomy.Performance for speed workouts and general runningFor speed sessions, I usually prefer using a treadmill because it allows for better pace control. While testing the ASICS Superblast 3 on the treadmill, I found the shoe slightly less suited for faster-paced workouts due to its chunky build. The extra cushioning and larger sole made it feel like I needed to produce larger strides.That said, for general running, outdoor speed sessions and longer outdoor runs, the shoe performed extremely well. The cushioning and support helped make my runs feel smoother and more comfortable, particularly over distance.Value for moneyAt £200, the Asics Superblast 3 are definitely on the premium end of the running shoe scale. However, the high-quality construction, advanced cushioning, and overall performance help justify the price in my opinion. The advanced materials make these worth the price.How do they rate online? The Asics Superblast 3 rate really well online with an average user score of 4.8/5. Most customers seem really happy with how cushioned and supportive they are for recovery runs, though some have mentioned, as I found in my testing, that they run a bit too large and bulky for slimmer feet.Asics Superblast 3 running shoesHow do they compare to other products? Compared to similar shoes such as the Adidas Adizero Evo SL (£129.99) and Saucony Endorphin Speed 5 (£107.99), the Superblast 3 offers a more cushioned and forgiving ride, making it particularly well suited to long-distance running. While those alternatives might feel slightly quicker during faster sessions, the Superblast 3 delivers a better balance of comfort and bounce.Runners looking for a more affordable option may want to consider the Asics Novablast 5 (£94) or New Balance FuelCell Rebel v5 (£83.99). Both provide a lively and enjoyable ride, but neither matches the Superblast 3's ability to perform across such a wide range of runs.

You might also enjoy a soft, highly cushioned ride, while others prefer a firmer and more responsive feel. Personal preference plays a big role here, as does understanding your gait.Also think about where you'll be running and consider comfort first. Road running shoes are designed for pavements and tarmac, while trail shoes offer more grip and protection on uneven terrain. A shoe that feels comfortable from the moment you put it on is usually a good sign. Don't choose a pair purely because they're highly rated or fashionable.You should make sure the fit is right too. Your toes should have enough room to move and the shoe should feel secure without being tight. Remember that feet can swell during longer runs.Finally, we always think it's good to test before you buy where possible. If you can, try shoes on in person and walk in them. What feels best on your feet is often more important than any review or recommendation.Get more expert advice on picking a running shoe in our full guide to choosing the right trainers.
