Adidas Adizero SL 2 Review: BEST Running Shoe Under £100 

I like from the start you said go buy these, no beating around the bush 🤣🤣. Just ordered mines in the black it's selling out fast!, very happy that I got it on discount. From all the reviews and the way it looks I believe I'll love it, one thing although their laces aren't special i don't have a problem with them untying in other shoes. 👍🏾

I just got a pair of SL2 and I absolutely love them!!

Mine arrived yesterday ( went for the denim blue colourway which remind me of my first pair of adidas running shoes from 40 years ago!!) First run this morning and from first few steps WOW!!! Big smile on my face all the way round. Fantastic adidas 👏👏👏 Oh just one thing Fordy I have average width foot but went half size up and they fit perfect so not TTS for me. 👍

Love your work. One thing to note about the SL2 is that the sockliner is glued in so not easily removable. An orthotic (at least my orthotic) won’t fit in the shoe. Ripping it out means buying the shoe while not knowing if it will accommodate your orthotic.

I agree with what you said. I got my pair and immediately thought they would pair well with my Boston 12’s and Pro 3’s. Not sure about you, but they reminded me a little of the original Novablast. It’s got that special sauce, but with its narrow heel it’s got a little bit of that insanity the original Novablast had, but much lighter and livelier.

Always straightforward reviews and very insightful to make a decision about the shoe. Thanks Chris.

I’ve just ordered some of these to replace my Novablast, absolutely loved the Novablast 2 but didn’t like 3 as much so wanted to try something else. Kept going back to Novablast 2 even though it’s falling to pieces! Really looking forward to trying them.

Hey man Thanks for the review I've been running in the asics noosa tri 15. Been wanting to switch to adidas and the boston 12 caught my attention. But since sl2 was introduced, i thought of holding out for this. I only do daily, tempo, speed and 5k and 10k races.

Good review. Funny that this shoe and the Boston that I backed are now very popular, adidss have upped their game big time.

Great video Chris, not that I need another pair of shoes but these will certainly be on the list, sounds like an adidas shoe that will finally work for me!

Yesterday they arrived and today I ran my first 10km and I loved. Great shoe, way too good for the price (100 USD cause adidas website had 20% off). Greetings from Ho Chi Minh city Vietnam.

It reminds me of an 80's football boot

Are these shoes narrow? When you reviewed the Puma Velocity Nitro 3 you warned us that they were narrow, and so I ordered the wide version, which fits to me perfectly. Your suggestion was spot-on! If these Adidas SL2 are narrow like their Puma rival, I would definitely need to look for a wide version (but it appears that there are none) or maybe for a size-up?

It’s like the takumi without rods and softer. Love this shoe

I just got them today. Great shoes for daily casual trainer.

Thank you I Love the video but I'm so impressed with these absolutely my favourite ever daily running shoe I liked them that much I went and bought another pair both in the same colour as on you video bought from ASOS first order 10% off bought today with a email promotion from ASOS with 20% off £88.00 and free postage

Could do with being slightly wider for my wide(ish) feet. Hoping maybe a wide version will come as they do in some other Adidas. Everything else about them I love.

Adidas is back woth a bang and SL2 will be shoe of the year all round.

Great review Fordy! I'll buy one soon! Can you also recommend a trail running version of the Boston 12 please?

Bought! Just wish the UK had Lime colourway

Great video as always Fordy. Would you recommend these for someone looking for a speed/tempo workout shoe as well as for tempo long runs? I was looking at the endorphin speed 4s and now I’ve seen this I’m not sure.

Great review. Full length lightstrike pro sounds great... Wonder what it'll mean for the Boston 13. And that colour is great too.

Great shoe. I chose these over the pegs 41

DO you think it wear/size like the Boston 12? I had to go 1 full size down with B12 compared with the Adios Pro3. Thank you.

These are on sale already on the U.S. Adidas site. You can get them for $91 with a promo code. Can't beat Adidas's sales right after launch 🤣. Had to get me a pair at that price.

How do you feel about it's narrower fit? Also do you find them sort of unstable? There are guys that love the shoe who said those things can be a deal-breaker for some of us.

How much changes does it have compared to the Adizero Sl 1

I remember the black plimsoles, I had to wear Dunlop green flash… for cross country… madness.

How's the heel collar and padding of this shoe compared to Boston 12? I find that part in AB12 stiff, thin collar, and rigid which can literally cause bruise to the back heel.

I’m a years and years fan of Nike’s Pegasus but seeing how they constantly add weight I just don’t think I like that direction anymore. I have the 40 now but the next daily trainer might be the SL2 🎉

How does this lightstrike pro midsole differ from the one in takumi sen? Thanks.

Adidas were shoes not on my radar for some time, no idea why they just weren't until I was persuaded to try a pair of Boston 12's by a friend, loved them, then I tried pro3 and loved them, then Prime Strung 2, Think i love them LOL. I picked up a pair of supernova prima, mainly because i like the colour LOL.... and as you were surprised by the SL2 I am super surprised by the Prima and guess what!! they have amazing laces, fab gusseted tongue, upper is really nice and its soft but not to soft, has a pop and a great roll off the toe. Oh and also picked up a second pair of Boston 12 in the colourway you have in SL2, again just for the colour, yep I'm such a girl. ADIDAS are my new fave shoes, they just seem to suit my gait and foot shape.

I bought these in my normal size, exchanged for a 0.5 bigger, and it's still small and narrow. Not sure how this is true to size. It's the first time that I have to buy a runner 2 sizes up from my "normal" size.

Is it fair to say it's a more durable Rincon?

Picked them up for 85.50! Size 8 from sports direct 😂

Adizero SL2 vs Propel V4 for daily trainer? I am in Wide Propel V4, thinking Adizero SL2 would be too narrow. I don't generally fit Nike at all.

Chris I was (am) thinking of adding the supernova rise to my shoe rotation with the winter months in mind, how does the SL2 compare to the supernova rise

Hi Fordy i find Adidas sizing very weird in every other shoe im either a seven and a half or eight but in Adidas i have to order a nine so unless youve got very narrow feet i find them being true to size very surprising. Be interesting to hear other people's opinions on this.

It's $129.99in the states. I know a few D1 College athletes that use them as trainers. They're better than the Nike Pegasus and are a solid daily work horse!

How’s the stability ?

Would it be a good shoe for a bigger runner ? 6’2 220 . The Mach 6 was too snug for me

Chris I find Adidas shoes quite narrow. Is there plenty of room in the toe box?

It's food for thought, but I shall wait a few wks. more when the Brooks Hyperion 2 come out to see how they compare. The Hyperion 2 will be different than the Hyperion 1 with increased stack height and an upgraded more responsive midsole. Plus, it's almost 2oz. lighter than the Adidas SL2 with a wider toebox. It's probably firmer, too, for us bigger guys like myself who like less squash. I already have the Boston 12, and the ratio between soft and firm is perfect for me. I don't like anything any softer.

Vs. Deviate Nitro 2? Is it unstable for that narrow midsole?

pls compare to the cumulus 26... :)

Hi Chris are the SL2 on the narrow side

I'm thinking of getting these or the Hoka Rincon3 as my everyday runners to complement my takumi sens. What do you think?

How does it compare to the Rebel v4 and Mach 5?

Great review Fordy, thanks. Great for me as I am an adidas fan with Solar glides and terrex 340’s and previously adizero’s. Can you please copy the promo code to us ( to use on the adidas site). Looking forward to your next review 👍🏻

Hi Fordy, are they the same length as the Adidas Adios pro 3?

How does it compare to the Boston 12 ?

I've been struggling with adidas since say, the adizero adios 7 and everything after that in the adizero line. Sorry adidas but I don't have triangular, pointy feet. Then the foam around the ankle integrated inside like that of the Boston 12 is not ergonomic for everyone. Because of that, my heel was slipping, very poor heel support. I wanted to give an Adizero a chance, it was a failure. I haven't tested the Supernova models yet but I would like to be able to appreciate this SL2. I really liked Adidas, the Adios Boost 3 was my best of all the shoes I tried.

Bought this and waiting it to arrive (about 90USD). Sadly only the white colourway available at Adidas Malaysia website for men...

Anyone know how the sizing is on these. Im always confused with Adidas. Im a Uk 9, I had the Adios 6 as a 9.5 (to long) and the Boston 10 as a 9.5 (perfect size) and Prime X in a 9 (perfect size). The Adidas website says I need to be a 9.5 in these.Usually a uk9 comes up as 27.5cm but a uk9 on the Adidas website is like 26.7cm(Try to use CM for consistency). Im so confused!

How does this compare with the Hoka mach 6?

Do these fit TTS?

great shoe

This is the puma velocity nitro killer

Please put the disclaimer in the show notes rather than in the video.

Sport Shoes have these for £98.99

Adidas sadly still not producing it in large sizes...

Sold out already on start fitness...gutted

The SL MK1 was so bad I couldn't run in them and I've got more shows than I have room for , honestly they where useless. These would need to be a completely different shoe to be a winner .

Under £100? I paid €130 in NL 😅 (fine for me but that’s a difference)

I have wide feet... these look narrow.
