I tried out the tip in some of my favorite pairs of heels that were all over three inches, some with big block heels and others with tiny stilleto heels. I'll spare readers pictures of my feet, but I dutifully binded my third and fourth toes first with tape and later (at the suggestion of the Bustle writer) with bandaids before slipping into my shoes.
Overall thoughts: While I did appreciate the cushion this provided, the pads kind of pushed my feet out in a weird way and made my foot do that overflowing loaf thing on one side. I thought maybe this would've worked better had my shoe been bigger, but as it was, I still had a little room in the back, so I don't think it would've actually made a difference. This definitely made the experience of wearing the heels better since it provided some arch support, but it wasn't a lifesaving experience.
Keep silica gel packets in your shoes when they’re not being worn. Have you noticed after purchasing a pair of new shoes those little white packets containing tiny clear balls inside your shoe box? Those packets contain silica gel which absorb moisture and keep your shoes from shrinking. Hold on to those packets instead of throwing them away and stick them in your shoes when you’re not wearing them. You can ask a shoe store associate for extras, if necessary.
