Yes, they look flat, but looks can be deceiving
I admit I wasn't impressed at first glance (they don't LOOK like they would make much of a difference when you hold them) but my feet think otherwise.  I've been battling tendonitis around my arch from poor support and adding these to my sneakers has made a HUGE difference. It's hurt my arch to put weight on my foot for the past 2 weeks and these offer the perfect amount of support for that, within a day my foot started feeling better and walking was easier.  Pain assistance aside, my shoes are so much more comfortable to stand in!<br /><br />Edit (after 2 months of use): I have noticed a huge change in comfort with these inserts.  I tried to switch my running shoes to their standard inserts and could definitely tell the difference. Reference picture: yes, they do seem flat and flimsy but notice that there is a definite padding in the arch area. It's not a drastic amount of support but, remember, most tennis shoes (and boots depending on the brand/style) have a small arch built into the shoe, this small amount of padding adds to that arch. Unless you have drastically high arches, you should feel a difference with these.
