This is the most important rule: Don’t buy wedding shoes unless they fit you perfectly. Just don’t! If your shoes are already too snug, you’re only asking for pain after an hour or two — or maybe less. And then you’re not only going to ache, chances are you’ll end up with a painful blister and will then fantasize about crawling around for the rest of the day — because even changing into flats is painful when you have a gnarly blister.
The Multifunctional Blow Dryer: On the other side of the thermostat, heat will also loosen your heels for comfortable wear. By blowing your hair dryer across the top of the shoe, you can make the shoe more flexible on a warm or hot setting. There are two options here: you can do this while the heels are on your feet or while they're off. If you're not wearing the heels, after blowing them with some warm air, twist the sole (or where they were hurting you) while they're malleable enough to loosen and break them in. If you want to do this with the shoes on your feet, grab your thickest pair of stocks and put them on before using the blow dryer. Concentrate the dryer on the parts of your shoe that were hurting you the most and move your feet around while the dryer is blowing. After about 30 seconds, walk around with the thick socks and heels on (stylish, we know) and break. those. shoes. in!

I used this product exactly as noted on the label, for my brother's wedding and I was able to wear my 6 inch platform heels comfortably for 9 HOURS! I must note that these are shoes I have worn many times and never had a blister or anything, but I was able to wear them much longer! I also used it with 4 inch heels only previously worn once(for 3 hours and without the spray) and they were much more comfortable and able to be worn for 7+ hours.I will be purchasing another bottle! Thank you!
Recently I was at a friend’s birthday where a few of us were debating the plausibility of walking home in  heels after a night of standing around. Now  I love heels, high high heels. In fact the higher the better. I love the line they give the leg, I love how elegant they make me look…..what I’m having trouble with is how they feel. After years of taking ballet and wearing pointe shoes you’d think I could handle heels but lately anything fancier than a sneaker is causing me foot pain.
Blast your heels with heat.[1] Heat is an effective way to soften a material and make it more pliable. Carefully warm your heels using a blow dryer or a small heater for about a minute or two. Watch how your heels react to the heat because certain materials don't do so well under heat for long periods of time. You can bend and twist your heels while they’re still warm. Or you can wait until they’ve cooled and put them on with a pair of socks to stretch them.
Stretch your feet before and after you put your shoes on/off. There are some targeted stretches that will help you get at the front of the foot and ankle (key pain points from heel usage). An example of a stretch like this is pointing your toes down, and pulling your toes up with a strap, this gets the Achilles’ tendon and the calf muscles going a bit. You can replicate this stretch to the inside and outside as well.
Keep silica gel packets in your shoes when they’re not being worn.[3] 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.
