In NZ, (I think 10%) duty still applies to shoes (except children's shoes below size 10). So, take the American price, convert to NZD, multiply by 1.1 * 1.15 and you get $221.375. There's also a $55 Customs fee, and freight and GST on freight.
Looks like the $245 price is a bargain.
If that's too steep for you, try the Warehouse for a $20 pair of shoes.
Not to mention the US price excludes their sales tax, so that needs to be added onto the US price as well at the time of purchase to make a fair comparison. So many people forget this when comparing prices.
