You can do two different sets of tips in order to prevent blisters and shoe bites or treat them when they have already happened. One set has to do with your high heels and the other one – with your feet.
You can also further improve the comfort by making sure your shoes fit well. Then, you can always DIY a on-the-go remedy with a band aid. Place it on the places where your feet hurt. Now, this may be a bit of a problem if you are wearing strappy heels or cut out shoes and the band aid is visible. A possible solution is to cut thin strips of soft fabric in the color of the shoes and stick them on the inner side of the shoe, where it hurts. There are even self-adhesive fabric strips to make it even easier. This will make it more comfortable and reduce the friction, thus easing the pain.
Another option is to make sure your feet are dry. You can use some powder or gel deodorant for that.
But sometimes it is just too late and you already have a blister or a shoe bite. There are a few easy ways to treat them.
For example you can apply some aloe vera which is a natural anti-inflammatory. It will relieve the redness and swelling. Another home remedy says you can soak your feet in green tea. Brew three bags in boiling water and add a teaspoon of baking soda. After it cools down a bit, soak the foot with the blister.
If the blister has popped, apply some tea tree oil on it. It may sting a bit, but it is a great way to disinfect the area and it will heal up much quicker.
You can also soak your feet in water with salt. This will help clean them and will be good for them overall.
