Memory Foam FootwearMemory foam, originally devised for the NASA space programme, has now come well and truly down to earth. Not only can you sleep on it and sit on it, you can even walk on it!
Shoes and SlippersThe application of visco-elastic foam to footwear is not a surprise. It was previously impractical due to cost, however the price of memory foam has become much more affordable in recent years. As a result you can now buy shoes, slippers, etc with built in memory foam cushioning.
Memory foam provides a combination of both support and comfort. It moulds itself to the contours of your feet. This can help to provide extra comfort whilst also supporting the foot. As always, if you have a medical condition then consult your doctor first.
Shoe InsertsThere are only a limited number of memory foam shoes and slippers on the market today. An alternative is to add an insert - also known as insoles - to your favourite normal footwear. Inserts are cheaper than buying a new pair of shoes and may well be the best option for some people.
For those who really like to "push the envelope" on footwear, it's even possible to buy memory foam inserts that also contain magnets.
When using inserts, be aware that they take up space and will make your footwear a little tighter. If your shoes are already tight then an insert of any sort might feel comfortable at first but actually result in pain and discomfort later.
