You end up wasting more money in the end. I have been using crocs for a long time now but this product didnt fit for my normal size and was too large, hence unwearable. The fact that the pillow is smaller than a standard pillow is not an issue, but once a pillow case is applied and the stuffing is rearranged, I sometimes find it difficult to find the ear hole in the night since I change sides frequently. I think it may be not so reliable as expected. Absolutely great value for the price. Now, I bought the Sketchers Brexton shoe from Khols and they have the identical sole and insole, and they came perfectly fine. 5? longer than the average size. The Totalprofitness pad is exactly what I wanted. They have taken some serious abuse on the trail, as well as the pavement, and still look nearly brand new. 10/10 recommend it
