Asics trainers- size up or down?

[slothycoffee]

If so, how much should I size up or down with Asics running trainers?

Thanks

My response isn't Asics specific, but with my runners I always go for one half size larger because feet swell when running. It's also worth knowing about "degree of drop", "pronation/stability" and "width of toe box" but I recognise you might know this stuff already.

I had to go one size up on mine. I got them online when I started increasing distance and my knees were complaining because I was using trail shoes on hard surfaces. It turns out that they don't have enough arch support for me so while they're better for my knees, I now have problems with my foot. I only realised this after a few long runs so it may be worth holding on until the shops reopen and getting a proper gait analysis.

Can I ask what problems you have with your foot? I went for a 10 mile run in trail shoes and half the run was on pavements and now my foot really hurts...

Oh no, sorry to hear that. For me it's the arch of my foot that feels really tight. At its worst I get a sharp pain every time I put weight on the foot when I walk on it. It doesn't hurt when I run though. Icing every time I go for a run plus strength and stretch exercises and rolling do help a lot. I do a few of these every day: healthline.com/health/fitne...

It doesn't sound like the same thing. My middle toe really hurts and my inner ankle. Makes it hard to weight bear. Having got up to 10M, I'm really dreading being told I can't run for weeks...

I'd recommend going a full size up. My ASICS are 1/2 size up - they felt (feel) fine in cold weather but as soon as the weather starts to warm up my toes complain.

I bought my Asics in a running shop and they told me to go up one full size from a 4 to a 5 and they have been fine. I need control shoes as I have no arches!
