Gym/Crosstraining trainers

[OtherPlans]

I need some trainers for modified HIIT/physio led exercises in a gym. I have sciatica on one side (probably due to frequent sitting/occasional wheelchair use). What kind of trainers do people use for hiit/gym exercises? My specialist has just said to get a trainer with lots of bounce. I have seen running shoes recommended for sciatica sufferers but don't think they're intended for crosstraining. Day to day I wear fitflop trainers and find them generally comfortable but they can't be used for sport.
I've spent the last month looking for trainers but can't decide. I'd like a breathable mesh upper (and preferably black). I heard good things about various Asics, Brooks, Adidas ultraboost (though might be out of my budget).
If you have sciatica and do crosstraining/HIIT what trainers do you wear? I'm a size 5 so can also fit boy's sizes.

I do crossfit and swear by my reebok nano x www.reebok.co.uk/women-nano x
Roomy in the front. Also good for a narrower foot are nike metcons.

They both look promising. Thank you. Which of those has most cushioning?

Don't buy Nike Metcons if you need/want cushioning/bounce. Metcons are deliberately designed with minimal cushioning for weight-lifting.

Nike Free Metcons DO have some cushioning:

but you're probably better off looking at trainers designed for running to get enough bounce. It's fine to cross-train in running shoes. Most definitely not fine to try and run in Metcons.

If you need cushion/bounce then running shoes are your only option really.

Soft cushioned running shoes you can buy easily: Nike zoom structure 23, saucony triumph model 17 or later, brooks glycerin, pretty much anything Hoka, Adidas solarglide, ASICS cumulus.

Thank you I've added all these to the shortlist. I'll also look at the weight (and price).

I have decathlon CrossFit shoes and decathlon running shoes. The CrossFit ones (domyos) are flat and are fine for the running involved (I don't have sciatica) which is probably 800 metres max in a session. I have the decathlon kalenji runners designed apparently for running up to 10km a week.

Decathlon website is crap. I get mine delivered to Asda for £3.

Thank you I've never looked there before

My tedious quest for sciatica friendly trainers continues
I'm thinking the adidas solarglide looks good. Anyone have them/know if they're true to size? www.amazon.co.uk/gp/aw/d/B08PC6KCT2/ref=ox_sc_act_image_5?smid=A3P5ROKL5A1OLE&psc=1&tag=mumsnetforu03-21
To complicate things I've seen these New Balance Arishi v3 though not sure they'll have quite as much bounce?

This where I go for the lowdown on running shoes - it's run by a guy with a footwear design background who used to create shoes for some of the big sports brands. His reviews are super detailed and very nerdy BUT his "best of...." shoe lists are a great place to start:

Basically the Arishi v3 are good value but perhaps not very cushioned or very soft.

Running trainers have plenty of bounce but only provide front support in the long direction. They are not great for twisting or lateral movements. Cross fit style trainers are supportive in all directions but not that bouncy! How about a netball or tennis trainer?

Thanks AOwl I'll have a look as think I need an expert view (I fell down a trainer nerd youtube hole and got very confused).
DublinDoris2000 that's my dilemma exactly. Basically a bouncy crosstrainer is needed. Netball and tennis shoes would be ideal. I'll see what's around.
Today I saw a feature on Altra trainers. A zero heel drop may be ideal or a nightmare.
