Up Close: Under Armour Blur CBN IV, Black Blaze Edition

UA Blur Carbon IV in Black

When it comes to boots designed for speed, the Under Armour Blur Carbon IV are definitely a boot on the list. Unlike its complicated name, there is an air of simplicity about the performance of this well balanced 7.5oz boot. I say well balanced because this boot has been evolved by UA to focus on more than just speed. Durability and a more adaptable fit make this a much improved boot over the Blur CBN III and give it a more balanced feel.

Featuring a Black/Electric/Blaze Orange design, these are a pretty impressive visual boot also. You get a more traditional style with a little modern highlighting to set it apart from other speed boot styles. Even though the upper material is not a traditional leather (it is actually a new microfiber material, called Wallaroo) it has a pure leather like appearance and keeps the boot looking clean.

Speaking of Wallaroo, it was introduced for the first time on this range. It has a soft leather like feel, but it holds the properties of a synthetic material. Right from first wear, it feels smooth and comfortable across the foot, providing a natural feel. If you are on the market for a speed boot that is built with durability in mind, these are definitely a top option. The Wallaroo synthetic upper is slightly thicker than your traditional lightweight material and offers plenty of strength through wear. They hold up very well and are also secured in place by an additional layer of material around the toe/soleplate joining. Durability is definitely a part of what these boots have on offer.

One of the key features of these boots is the BZM soleplate and the conical stud configuration. I mentioned in the Break In section how these boots feature a spine through the sole, designed to add strength. It serves a purpose but initially it feels stiff and you need to be patient as it adjusts to your movements (or as you adjust to the feel). This is the same system we saw in play on the Blur CBN III, so it has got the thumbs up during a prior review. In similar fashion, the conical stud configuration is the very same as we saw on its predecessor and we also give it the seal of approval. Where they are particularly effective is on AG surfaces, as the low profile keeps you close to the surface without causing any drag. In play, you can definitely feel a difference in how they break the surface and in a positive way.

Final note, especially for those considering a pair, goes to sizing. There is a definite tight feel about these boots and they have an almost Puma-esque style about them. In saying that, there is a slightly longer feel compared to other UA boots we have seen released in the past. With those boots, ordering a half size up was a must. With these, the option of choosing a half size up should definitely be considered but it it not a must.
