Pretty much every pair of Sketchers shoes now has memory foam soles and everyone seems to think they are great but I hate them.
They are really hot, the foam is like a layer of insulation.
The top of the memory foam soles is somewhat elastic so it’s really smooth and slippery so your socks slide around inside
They are no more comfortable than regular shoes and in fact I think they provide less arch support since they are squishy compared to shoes with harder foam.
And most of all the memory foam gets smashed and wears out in no time with some shoes having the foam glued in so replacing the insole is impossible.
I just can’t fathom how they are so popular.
Until you step on anything sharp or hot and hurt yourself
This is why barefoot shoes exist, e.g. Vivobarefoot. Thin, puncture-resistant soles that prevent puncture and slice damage while still allowing your feet to remain connected with the ground and get stronger.
Hadn't heard of those, they look comfy at least, although I'm not sure if I would call that barefoot, but of course I haven't tried them
The Primus outsole is around 2mm thick. It's a night and day difference compared to a normal shoe. I actually think the whole "we need arch support argument" is sorta overblown because I have super high arches and had issues with my feet pronating in, putting stress on my knees, and since I've swapped things got much better. You change how you walk, so you don't slam your heels down like most do, instead relying much more on Achilles and calf muscles. My foot fascia feels stronger as do my calves after daily walking in vivos, and this was noticeable a few months after swapping. The first week was the most odd, as you somewhat have to learn how to walk to not have as much impact (let your calves be the "spring" and land midfoot or ball of foot) especially on things like concrete.
Interesting, my arches are pretty flat though, so I'm not sure how well those shoes would work for me? I feel it would put more strain on my ankles and knees
That's the beauty about it- it doesn't matter. Your body gets stronger and adapts. That said, make the transition smooth to avoid injury. Listen to it as your work up the step count and mileage, and explore your strides and how you rebound in the step to find something that feels strong and doesn't facilitate pain. The classic shoe community is all about "how can we build a shoe that protects your feet from discomfort" whereas the barefoot shoe movement focuses on "how can we strengthen our body such that the protection isn't required". There's obviously a balance, and that's why barefoot shoes still have things like soles to prevent injury from sharps and provide traction.
