5 finger shoes, no, no, no, seriously...you didn't...not in front of Greek men; I dread to think what they thought, them sitting there, playing tavli and having a gylko coffe and you walking past! I used to believe in the ankle support idea, still do I suppose but over the years I've had two mates have broken ankle bones and they were in boots, to really give support they'd need to be tight enough to cut off the blood supply. I wish I was fit enough to put boots v shoes to the test:vio:
Use what you like, live and let live and all that.
I told you i chase new ideas and technology round the parking lot
They are very comfortable after your feet have got used to them, biggest problem i have is me Mrs keeps hiding the bloody things though, although you do get some weird looks, but then i tend to get weird looks no matter what i wear
I disagree with you on the ankle support.
Sure you could still twist or break and ankle in most hiking boots, but they still offer a hell of a lot more resistance to ankle injuries than nothing (i.e, shoes).
Best way i can think of describing it is, it's like wearing a helmet on a motorbike.
Yes you can still get serious head injuries but the injuries would be a lot worse without it, the same with boots.
Hope you get well soon mate.
Most hiking shoes/trainers have vibram soles these days, the same as boots funnily enough.

The soles on my Hedgehogs are nearly as stiff as my Miendl boots.
Seems that the ones you tried may not have had Vibram soles?
Vibram make many different types of soles and they differ vastly in both density and stiffness.
As an example obviously my Vibram 5fingers have a sole made by Vibram, this is very thin and very flexible.
Where as the Vibram sole on my hiking boots is a LOT thicker and offers a LOT more support.
The Vibram soles on my approach shoes again are very very different than the Vibram soles on both my hiking boots and 5fingers.
So not all Vibram soles are the same.
Vibram is a brand name not a product, think of it like Ford.
A Ford Fiesta is very different to Ford Transit van, yet they are still manufactured or assembled by Ford.
The other thing is, the construction of the shoe/boot has a MASSIVE effect on the soles stiffness.
You could fit the exact same sole on say a sandal and say a boot and they both would feel very very different.
The times i've bothered taking my GPS with me i've averaged around 80km hiking.
This is out walking the dog, hiking with the kids and just out walking and backpacking to relax and have fun.
In my experience after around 12km i generally feel less fatigued in stiffer soled hiking boots than i do when i'm wearing my approach shoes.
Throw a fairly heavy rucksack into the mix and i strongly prefer stiffer soled hiking boots to approach shoes, even though i have the option of both.
I have done longer hikes with a heavier backpack in approach shoes and i did complete the hike.
BUT i felt noticeably less fatigues in stiffer soled hiking boots.
On smoother paths, over shorter distances, with shallower gradients, carrying less weight i would select approach shoes over boots.
On a 22 mile hike with a fairly weight backpack it's a no brainer for me, i would prefer not to do it at all over having to do it in approach shoes.
This is with my experiences with my legs and my kit.
