We noticed that many of our customers were buying the 6 cm and 3.5 cm height increasing insoles together. The reason seems to be that they want to use the insoles as per the occasion and type of shoes they were wearing at a particular time. Hence we are now offering this combined deal, which is cheaper than buying the two items separately. All savings in courier, packing and handling cost is being passed to the customers in form of reduced combined price. This is value for money deal.
