these insoles changed my life ;-)
If you have very high arches, you know, the kind that Superfeet and drugstore arch supports don't remotely support, then you should try Sole insoles. I was introduced to them by my ski boot fitter, who heated and molded them. But I've since bought 4 more pair and use them as is, without heat molding. They're an aggressive arch, perfect for my foot. I use them in my bike shoes, hiking boots, and more. Because of them, my big stiff hiking boots are more comfortable to walk in than my sneakers. Various nervy pains that I get in certain flat-footed shoes are gone with these arch supports. Anyway, for someone who went decades not realizing she needed arch supports, using these has added another dimension of joy to my life ;-). Really good stuff. And cheaper than custom insoles. My shoe size is 40 european or 9.5 US Womens. I've found the Sole mens-7/womens-9 fits my boots/shoes perfectly.

Sole Best Footbeds
Sole thin footbeds are the best I've ever had. Perfect in my Lowa Men's Tibet Pro boots and my Danner mountain lite boots. If using the Sole Signature EVA Ultras - go half size up on the boots, unless they are already loose.

Solved foot pain!
I have tried numerous other footbeds for my arch problems. This product is by far the best I have used. I can now walk all day and not have foot pain. I have a pair of the thick pair as well. They can only be used in my running shoes but are excellent as well, though I prefer this thin model for all other shoes including my hiking boots.

Incredible!
Sole makes the best aftermarket insoles available. They offer great support and are incredibly comfortable. I use these in two pairs of my cycling shoes, I have the size 11 insoles for my Pearl Izumi shoes which are size 46.5 and 47 respectively. Heat molding these insoles creates such a seamless fit that is perfectly conformed to my feet for the best comfort! I highly recommend the Thin Sport insoles to anyone looking to add another level of comfort and support to lower volume footwear!
