The big number on the forefoot of a Blueprint or a Stomp indicates the size for a man. There's a 2 size difference between men and women. Example: A men's 6 is a women's 8. A women's 9 is a men's 7. We recommend using the same size Ready-Fit as the shoe you're putting it in. Round down for half sizes. Example: a men's 9.5 foot generally fits nicely on a 9 Ready-Fit. Don't hesitate to trim the forefoot to match it up with the length and shape of the stock insole, and to get it to lay down flat in your boot or shoe! 

5 years is typical. Some are still going strong after 10 years!

The enhanced comfort is obvious, but the main reason is actually performance! After 30 years of working with World Class athletes, we're convinced that it's imperative to still allow the foot to adjust and balance naturally when providing support. If your foot is over supported due to overly hard materials, you tend to lose "touch" and "snow feel". More is not always better when it comes to foot support in athletic footwear!

We stand behind the quality of our Ready-Fits with a guarantee: If for ANY reason your feet aren't happy, or if the insoles fail to last through a full season of use - whatever that means for you - we'll either send you new insoles or provide a full refund.
