By cons I am very happy with this product for cleaning insoles and sandals. Here's why I'm glad this product:
1- The usage is simple: wet section clean, we move a blow to remove any stains, the product is applied with the tip "sponge", I leave in contact a few minutes and then rinsed.
2- This was effective in removing odors taken by leather sandals (barefoot port) and orthopedic insoles.
3- This product is not fragrant and is not particularly irritating (user observation allergic to many perfumes and intolerant to many chemicals). As the use is fast and rinsing, is not exposed long.
4- I feel really use some product with each washing. So I think I can make a lot of washes with this bottle.
