This week, we've got new shoes from Fizik.

I mean, who doesn't like new shoes.

These are the brand new Fizik Vento Powerstrap R2 Aeroweaves.

Very swish but that's not all.

That's not the only pairof shoes we're giving away.

We also have, the Tempo Overcurve R4s.

Pretty good, huh? Now before we go any further and show you how you canwin and get your hands on these awesome shiny new shoes.

Right, I'm going to start off with the R2s so let's put this oneto one side, the R4s.

This is a brand new show from Fizik and they claim that it's the lightest, stiffest and most breathableshoe they've ever made.

Oh, wow, take a look at that.

This incredible mesh upper structure is actually made from nylonfibers that have been interwoven with filaments of a thermoplastic polymer.

And it crates a reallystrong upper but one that also has, well it'sgot this mesh structure which means it's great for breathability, there's loads of holes init, and has added bonus, I reckon you can seethe color of your socks through it, as well.

In fact, I'm going toput that to the test now.

Ah, yeah, look at that.

You could have some fun with that.

I reckon pick ones would look great.

That's an impressive amountof venting in these shoes.

Now the closure is Fizik's Powerstrap, which is the same as on the other Powerstrap shoes Fizik make.

I'm a big fan.

You've probably seen mewearing then in videos.

Now this is a Velcroclosure, unlike a sort of boa dial and that's good'cause it's nice and simple and it gives a nicesecure hold and it's easy to sort of adjust and tune your fit and it's nice and lightweight too.

But it's not just astandard Velcro closure like you'd get on astandard pair of trainers.

It's a much more comprehensive one that wraps around thefoot and it's said to act like a ribbon to give youa much more secure hold.

The soles on these bad boyslook rather cool as well.

Now they're fully unidirectional carbon, and they're said to be thelightest and stiffest soles that Fizik has ever made.

Stiffness index of 10 written on there.

And another important detailis the cleat hole positioning has been moved slightlylower into the mid-foot area, more so than it was on previous shoes, and this is to help with the ergonomics of those more aggressivesort of time trial peddling positions that people often like to fix their cleats in.

More mid-foot.

Now, the weight of theseis really impressive.

We've put them on thescales and they're coming in at around 205 grams for a 42.

A little bit more for these 44.

That compares to the Powerstrap R5 which is around 500 grams a pair, so about 100 grams lighterthan the R5 Powerstrap.

Having just come out, the R2sare currently only available in black but to be honest, I just think they look absolutely awesome.

They're a very race orientatedperformance orientated shoe.

If you're after somethinga bit more relaxed, then maybe the R4 Overcurveis more up your street.

So let's have a look at that.

(upbeat music) So the Tempo OvercurveR4 has been designed as a bit more versatile all-rounder.

Now to be honest, I just think the coolest thing about it is these color options.

Look at those.

That's mad.

So in addition to thestandard sort of monochromatic black and white colorsways, Fizik has also made the R4 Overcurve available inbeetle black and copper black, which this is the beetle black.

It's this incredibleiridescent paint scheme that kind of changes with the light and the angle that you view it from.

It really does look spectacular.

I hope this is comingthrough on the camera.

You've got a bit more of a classic look to these shoes as well, with that nice sort ofsingle boa dial as a closure rather than the Velcro on the R2.

Boa dials, if you're unfamiliar, are the kind of goldstandard in retention dials that come on performanceroad cycling shoes.

And you can micro-adjustthem with just one click on millimeter increments, nice.

The soles on these shoesare carbon composite rather than the fullcarbon that's on the R2.

They're 15% carbon injectedinto the composite material, and they're given astiffness index of seven verses the 10 on the R2, soa little bit more forgiving, which Fizik says correspondsto a bit more sort of flex and a little bit more comfort, 'cause sometimes really stiff carbon shoes can be a little bit unforgiving.

They are very performance orientated.

Now as you'd expect, the R4is a slightly heavier shoe than the R2, but not by much.

They're about 256 grams pershow in an equivalent size so about 50 grams.

Still nice and light.
