Reddit reviews Blue Bellies 8 Inline Skate Wheels 76mm 78a, Clear/Blue

In general you can go smaller with wheels, but you can't go bigger than your frame's max allowed wheel size.

If you get aggressive wheels you're talking 52 to 60mm...with 58mm probably being the most common. They're all going to be a lot harder wheel between 82A and 92A with 88A probably being the most common.

For the skates you linked to you can use aggressive wheels, but the frame will be so close to the ground that your break will constantly be a bother. So if you get them you're gonna have to remove the break and learn how to stop only with drag, T, and hockey stops.

A final consideration point, is that aggressive wheels are a rough ride. If you're going to be skating casually for an 8hrs shift...the last thing I'd want is hard wheels.

I'd recommend some 72mm 85A to 88A wheels as a good middle ground between size/comfort/hardness/acceleration/easy of riding over rough terrain. These would be great

Also if your budget can't afford the ones I linked above, try buying some no-name generics and see how they fair for you. These at $20 are a no-brainer to give a shot

I'm using these on my Aero-Z. You have buy 8, but the price is good. You want 78a in hardness because it will give you some shock absorption.

I don't like the way they've designed the spacers (get spacers from a board shop), so you probably want to get some of those, and some bolts unless you have no problems with the stock bolts.

You may need bearings, too, unless can get them out of the stock wheels (I can't). Board shops have these, too. Just get the cheap ones. You're not skating.

In case the link doesn't work, they're Blue Bellies 8 Inline Skate Wheels 76mm 78a, Clear/Blue. $19.44 at Amazon.

Sorry if some of this is redundant--you may already know a lot of it.
