Excellent method to custom fit supports.
This is a versatile and effective insole/orthotic. There are pairs of inserts that you can affix to the insole (or the inner sole of the footwear, thought placement would be tricky). They vary in size, but have the same height. You can build up to achieve your personal need by placing smaller insert on top, creating a dome-like shape. The orange inserts are 'normal' and the yellow inserts are 'softer' cushioning. You can stick with one form, or mix them. For example, a firmer bottom insert with a softer upper piece.<br />A word of advice: If you plan to use the cutting guide, and not the existing original insole as a template (maybe it's glued in and can't be removed), then cut larger than you think is necessary. Then you can fine tune the cut for a perfect fit. If you cut too short, there's not much recourse.<br />I like that you can start with this product as a cushioned insole, and gradually build up for arch support. Further, appreciate the option to customize the softness of the arch support. I put this into my winter boots, with soft arch support, and it feels great. My shoe size is mens 8.5, and it's near the lower end of this product's Medium size. I think I cut along the lines that measure for size 9 (checking that it seemed larger than the existing space). Lo and behold, it fit perfectly into the boot. Maybe boots have extra space, more than sneakers or regular shoes. But, this is the very reason I advise cutting larger and then fine tune your adjustments.<br />Overall, the product appears to be constructed of quality materials, similar to other insole/orthotic products. It is not as stiff as other orthotics, which I prefer. (I don't require an orthotic, even though i don't have normal arch levels. So, i use cushioned insoles which give a gentle arch assist/support.) I used the softer insert, for a gentle slope and support. At this point it's difficult to assess durability. It seems to be made with quality materials, similar to other insole products. However, if it deteriorates quickly, or affords less comfort/support, i will amend this review.<br />I like the concept and implementation of the assorted shapes and stiffness of self stick inserts, with a cushioned formed insole. This product earns a 4.5 - 4.75 star rating, with a very high level recommendation.
