The KD9 Elite is very similar to the original KD9. The only difference is the new upper material and lacing setup. Opinions on these changes vary: Some feel like the new lacing system is an improvement that provides better fit and more lockdown. Others feel like it makes the shoe even narrower and almost impossible to wear for wide-footers.
When it comes to performance the KD9 Elite is very similar to the original KD9. The most notable difference is the strong lacing cables which slightly enhance support and lockdown. However, this new lacing setup also makes the shoe even narrower which led to some pain on the side of my feet.
It's a very specific shoe. Great if you have narrow feet and you are looking for a shoe with a lot of cushion and impact protection. If you are a shifty guard who does a lot of crossovers and cuts then the lacking support of the upper and the slightly unstable platform are not ideal. Not recommended if you have wide feet.
