sure, but age = length of time how unrecognised issues (exacerbated by work/sport activities) can and often do affect how one walks. That's obvious from the state of plenty of middle aged folk I know!
My benefit from superfeet IMO was from the alignment given from the heel cup to the arch shape, rather than 'support' per se. I already had high arches naturally.
Dunno so much, i spent more time injured when i was younger than now i'm older.
Sure our bodies aren't as fresh, heal or recover as quickly, but we also tend to be a lot more careful and cautious when we get older.
T'other thing is that selecting insoles based upon our own self assessment has just as much a chance of doing more harm than good.
These are corrective in-soles, if they're designed to correct a problem we don't have then at best they're no more use than the standard soles, at worst it could cause more injuries.
No doubt that they work for some folks, i just think that it's not advisable to just pick up a pair just because a person "thinks" they need them, best to go and see a professional first and take it from there.
With regards to arch support, please take into consideration that i'm no expert by a long long way, even the experts tend to disagree depending on who you speak to and when, or what articles you read.
From the stuff i read and discussed i'm of the opinion that arch support is NOT a good thing.
From my readings and discussions i found that many professionals felt that although the arch is an extremely strong support (like a arch in architecture) it's only really the top that offers any strength.
At the bottom of the arch where a high arch insole will be in contact with, it's a very very weak part of the foot.
By stuffing a arch support inside your foots arch you're transferring force that would have been taken by the stronger top section of the arch.
Not only does this put strain and stress on the vulnerable, weaker section of the arch, even worse is the fact that if you wear these high arch supports over time you'll be worse off, as your upper section of the arch will get weaker and weaker.
As i say i'm no expert and if they work for you then it's all good.
But if your interested it might be worth your time doing a bit of searching and reading up to see what opinion you form.
If you do it'd be fantastic to read your thoughts, especially if you disagree because as i say it's tough to find a good consistent opinion from the experts.
Personally though at this moment in time, i'm a believer that IF you don't have a problem that's been diagnosed by a professional then it's best to leave well alone.
The least amount of support (again as long as you have no diagnosed problem) you can get away with the stronger and less injury prone your feet are going to be.
