Blades size advice?

So currently I'm using the Matrix Legacy in the size of 10 1/4 and my boots is Edea Ice Fly in the size of 275. I'm looking for updating my blades to Matrix Supreme in the same size, but I came across this website that sell the Matrix Nova with a very reasonable price, the only problem is that the Nova blades is slightly longer, which is 10 1/2. Is it okay to use the Matrix Nova or should I just stick with the Supreme, since I'm really fond of these blades rocker profile.

The Matrix Supreme (and Matrix Legacy) has an 8' radius main rocker; the Matrix Nova has a 7' radius main rocker. So if you're happy with the Supreme, you probably don't want to switch.

Also, what is the actual lengths of the outsoles of your boots (front tip of toe to back tip of heel)?

I couldn't remember, sorry :(... But is 1/4 inch that much of a difference?

Edea recommends a blade length that is the full length of the outsole (but a 1/4" shorter is OK according to personal preference). So, assuming your current 10-1/4" blade is already full length (you need to check!), a 10-1/2" blade would be too long (among other factors, part of the heel mounting plate would jut out past the heel of the boot). So it's important to measure the actual lengths of the outsoles before proceeding.

Also, you should double check with Jackson Ultima. They no longer list the Nova under their Matrix series blades. If you Google "Ultima Matrix Nova", it does bring up a separate page (possibly older). One online retailer states the Nova has been discontinued and is holding a clearance sale. If this is true (again verify with Jackson Ultima), do you want to switch, knowing that you might need to switch again for the next blade (depending on availability of discontinued Nova in the future)?
 
When I have tried blades that were a little too long or short, I wasn't very happy with the results.

AFAICT, the overall length (which, AFAIK, is actually the distance from the back of the heel plate to the front of the toe plate) to some extent changes the lengths of more than just the overall blade. It also affects the length of the spin rocker segment, which affects how it interacts with the ball of your foot. It also affects how far the foot can roll forward without touching the toe pick - which affects things like scratch spins. And of course it also affects the effective length of the tail.

Conceivably an extremely expert skate tech could make modifications to compensate - but they would charge extra, both for that time & expertise, and because you didn't buy the blades from them. I'm guessing you don't have the tools and expertise to do it yourself.

And some very expert skate techs might advocate starting with a slightly long blade (but trimming the length of your tail) if you have extra long toes and metatarsals, because that puts the parts of the blade that interacts with the area around the ball of your foot further back.

But it's not normal, and not the way the blades were designed to be used, for what they consider to be the typical person.

Ultimately it's your choice.
 
A bargain's not a bargain unless it meets your needs. If you need to pay a tech to perform major surgery on the bargain blades (assuming you can even find a tech with the right skills and equipment), you will likely find that whatever savings you first got will rapidly vanish.
 
10 1/2 is the more correct size, but 10 1/4 is fine too.

That said, if you are happy with a particular blade in a particular size, I wouldn't change it. But the 10 1/2 will fit 275 Ice Fly (I know, because I've had that).

Hope that helps!
