Guides
Four questions worth answering before you spend anything, each one argued from the numbers in the database rather than from opinion.
How much height is believable
There is a point where a shoe stops looking like a shoe. Where that point sits depends almost entirely on the shape you chose.
Elevator shoes vs insoles vs platforms
Three ways to buy height, and they are not competing for the same job. The prices give it away.
How elevator shoes fit, and what size to order
They do not fit like ordinary shoes, and returning a pair from overseas is slow and expensive. Get this right first.
What a centimetre actually costs
Height is not priced by the centimetre, even though it is sold that way. The catalogue shows exactly where the money goes.
