Can you provide some additional details on your project? How long do the labels need to stay in place? Are the shoe dots going inside of the shoe?
If you are looking for something that needs to permanently stay in place under a person's foot, I don't think that our product is going to be a good option. The top coating on our waterproof labels would wear off causing the print to degrade.
There are companies that pre-print labels for this specific purposes. The adhesives are especially made to perform on these fabric surfaces.
In regards to labels for shirts - our product is not going to stay adhered through a wash cycle. It would work as a name tag for an event, but it could be removed and it definitely would not last in a washing machine. You would need to look at sew-in labels or something that is ironed on. There are also companies that pre-print these labels for this specific purpose and they use special printers and special fabric adhesives for longer term adhesion (companies like http://www.mabelslabels.com).
I am happy to send you some samples of our waterproof inkjet labels for testing, but I am not confident that it will work for your purposes if you are looking to permanently label items such as apparel or shoes.
