to copy a post i just put in the korfball.com forums:
I recently spent hours and hours trying to find where i can get korfball shoes in the UK. After reading a load of old threads on here and doing a LOT of googling, I found a couple of websites that do the shoes. There are several different shoes listed under "korfball shoes" but the ones that i think everyone knows are Asics Gel-Crossover. I found that they exist in mens and womens versions, a few different colour options and in 4 different "editions" with 4 being the most recent.
Unless your Dutch is good, you'll need to set your browser to translate!
So the first site is this:
http://www.korfbalshop.nl/korfbalschoen ... -hoog.html
they do free shipping to the UK but i had problems with putting my address in so had to find another site.
http://www.onlykorfbal.nl/korfbalschoen ... -2_19.html
this site do charge for shipping (around 7 euros if i remember) but the shoes are actually ten euros cheaper! you can also pay directly with paypal without having to put in a load of details
hope this helps people out, i know from reading the old threads that people were finding it really hard to get them in the UK.
