New shoes are nice, but blisters on the feet aren’t. The places they’re likely to show up are known hotspots, and these tend to be the heels, tops and sides of toes, as well as the sides of the feet where the bones rub against the shoes.
The reason for blisters on feet is the constant friction between the skin and the shoe. Finding out where hotspots are is easy – all it takes is wearing the new shoes around the house for 30-60 minutes, and then where there’s discomfort there will usually be blisters. From there, all it takes is some surgical tape, blister plasters, or even a substance that cuts down the friction on the hotspots to ward off those dreaded blisters on your feet.
High heel wearers, people with dry heels, and athletes usually tend toward blisters on their heels, which can be avoided with dedicated sports heel blister plasters, sports underfoot blister plasters, and high heel blister plasters. These are designed specifically for the type of shoe and movement expected of these wearers.
Similarly, you can consider gel insoles or heel pads in order to alleviate sore feet.
