A friend of mine that manages a boot store met the sales rep for super feet and learned how to properly size the insoles. What he found out is normally you need one size larger than your shoe size in order to get them to fit your arch properly. I got one size larger and they are very comfortable in the mountains. You just cut the toe end down to fit your your boot. Good Luck
I have the lowa sheephunters and wonder if it is better to keep the factory insole, or go ahead and get some superfeet. The factory insole seems a bit stiff, but still comfortable enough. Just looking to see if anyone has made the switch.
I put superfeet in my lowas sheephunters after I had about 20 miles in them and figured I'd give them a whirl. Glad I did. Now I have a pair in all my hiking footwear. The work really well with my foot anyways. Good luck.
After a good hike around the neighborhood I have to say that the superfeet are the bomb. Much better than the stock insoles. Good recommendation on the .5 size bigger for fit. Fit perfect having a little extra to work with.
