I have purchased this product for my mother and they have proved to be very sturdy and resilient when they were applied to the size 9 boots. They look minimalist on the boots and would not affect the model, the boots still look good with them applied. You can walk easy with them when is slippery outside.
However, you need to keep in mind that after entering a space with marble in a store or church you must be very careful as the coils themselves would slip on the marble.
Otherwise, you can have long walks on the snowy, even icy pedestrian side streets and not fall.
