Extra insulation + extra padding = year-round comfort
I bought one pair of these insoles over a year ago, and liked them so much that I recently bought a package of two more pairs.  In winter they do a good job of insulating my feet from cold floors and cold ground.  They're comfortable in summer too -- they don't make my feet too warm, and they provide an extra layer of resilient padding that's very comfortable to walk on.  They're also durable -- I've been wearing the first pair in my tennis shoes for over a year, winter and summer, and they're still nice and cushiony.<br /><br />Of course they do take up a bit of room inside the shoes.  I removed the gel insoles that I had been wearing in my tennis shoes and replaced them with these when the weather got cold fall before last -- and they've been there ever since.  They provide enough extra padding that I don't miss the gels -- and my feet don't get sweaty like they did with the gels.  I had to get a new pair of my long-time favorite Haflinger Grizzly wool clogs, one size larger, because there wasn't quite enough room for the extra insoles in my old ones.  The new combination is so comfortable and cozy that I may be loathe to revert to my old pair (sans insoles) in the spring!
