Just caught a glimpse of your post in the Community email update. I thought I might be able to offer something that might help you decision.
I have struggled with joint pain throughout my body since a teen (cartledge issue).
Up until my early 20s I had all kinds of insoles and supports. off the shelf, from professionals. All with a view to help straighten me up and alleviate some of the pressure on my knees, hips and back.
Then I discovered Vibram FiveFingers (iirc via Stuff Magazine)! I got my first pair of VFFs c2009 in Sheffield at a place called Naked Ape. A great experience. properly measured, solid advice. everything retail should be to be fair.
I have had various models/variants over the years. I pretty much wear them all year round since the launch of the insulated high tops (Trek Ascent).
My wife thinks I wear them for the attention. she’s kinda right! I get stopped by folk all the time “look at his shoes!”
But above all, the comfort, the grip, the flexibility. My walk is straight and strong and I have incredible balance. Letting my body do the work, building up the muscle/s groups and not relying on aids and additions. Isn’t what we’re designed for?
I’m not saying you should definitely get some. or that they will work for you. I hear some don’t take to them like I did. Others it’s taken a bit of “getting use to”.
What I would suggest is that you get in front of a retailer that knows the product. Get properly measured (you think you know your foot size. you don’t. trust me!). The Vibram experience is not what it used to be here in the UK (compared to the US). Online there’s a lot of fake/copies.
Here are some of my favourites
Ps, you can but you don’t have to wear socks with them. Some it doesn’t make sense to.
Oh! The fit, it’s supposed to be close. like a glove. If you move around in them, they aren’t the right size IMHO. And you don’t need straight toes to wear them. lol
