Recently took up gravel and decided my SpeedPlay cleats just couldn’t cope with the dust. Shopping around, I have to admit, I was drawn to these Fizik’s largely for aesthetic reasons – the look like a road shoe and come at a bargain price. I’ve been very pleased so far. The sole isn’t as stiff as my road shoes, and I’m told that is a good thing for gravel anyway, they’re easy to adjust and to walk in. They’re not super easy to clean after a dusty ride, but that’s probably true of most shoes. I’d definitely get these again, though, and might consider a road Powerstrap pair when it’s time for a replacement, too.

I really like these. Theyβre stylish and clean looking. I wear a 9-9.5 in womenβs shoes and I ordered a 41 because my work boots and my tennis shoes are a 41, shouldβve maybe ordered a 41.5, theyβre pretty slim and after about an hour my feet are ready to get out of them- but Iβve only had them a couple weeks so could need to wear them in. All black was unavailable on the Fizik website, so I found them here for the same price. Happy with them, would recommend. Also should note Iβm using these on an indoor spin bike with Venmo SPD pedals.

I didnβt know what to expect with these. Having moved away from traditional road shoes to MTB variety of the last few years (mtb shoes seem to wider overall) fizikβs gravel specific shoe sounded interestingOk. So. For real. They comfortable. Yes they are narrow (i dont have a super wide foot @ 13.5) but not insanely narrow. The straps make the shoe a little more forgiving up top (some give over what youβll find with a ratchet or BOA system)Iβm using them with SPDs. No issues with clearance getting into the pedals or flex around the cleat area when pedalingHopefully they stand up to heavy use

-Surprisingly good power for a gravel shoe, these provide very good power especially up hills on narrow gravel tubeless tires on either pavement or trails and they just so happen to mesh perfectly with my SHIMANO PD-M9120; XTR; SPD Flat Bike Pedals.-These look like road shoes, but are very much meant for a pure gravel experience. The velcro is really nice, allows for quick and easy on the fly adjustment for the toe box, and are super easy to get on and off quickly… I actually now prefer velcro over the boa systems on other shoes after having run with them the last year and hundreds of miles.-As others have mentioned, the toe box is not meant for those with very wide feet so if you are one of those you might need to look elsewhere. I generally have a normal – slightly narrow sized toe box and a high arch feet and these fit excellent without any pressure/numbness after a 20 mile ride.-My Dad also recently wanted a pair of these after seeing mine because he really doesn’t like most road shoes/cleats due to how annoying they are to walk in.-These you can walk around everywhere effortlessly and comfortably with installed cleats as they are more level to the ground surface and traction meant for walking the trails too.

It was a great relief after buying 6 other pairs of cycling shoes to finally find these that have accurate sizing. Their original strap design works very well with two straps doing the work of three straps quite effectively.The shoes use a two hole cleat and the cleat is recessed so no issues with walking on any surface, even hardwood floors, while wearing these shoes. With their firm soles there is no need to invest in sxpensive 3-hole SPD-L cleats and pedals and cleat covers.

I got this to have something a little more ‘road’ yet with SPD pedals for my gravel bike (which I ride on road and gravel). I had been riding some giro mountain bike shoes that breathed well but got a little torn in a crash. These are more stiff up top but are comfortable still. The straps work well and are nice and sleek, though with the stiffness of the upper I don’t always feel snug around the front of my foot. good room in the toebox. Not super breathable but I haven’t gotten super hot either (I avoid riding in the heat of the day though).Only main complaint is I wish there was some tackiness/grip in the middle of the sole as when you can’t quite clip in automatically it’s nice to still be able to turn the cranks coming off a stop light, etc. Don’t do that in these though as your foot will slip off as the underside is hard and slick except for the tread spots at the front and back.

I like this shoe a lot, my first clip less shoe. Velcro is convenient and I donβt have to worry about laces. Nice understated yet tasteful, clean design.I only have two concerns. When I walk, the metal cleat makes sound, so I donβt know if they will scratch floors if I run into a store. Second, Iβm worried on really long rides the toe box will squish my toes. Weβll see, I guess.

They are decent gravel race shoes but run narrow and small. I found them to be too uncomfortable, especially if you do rides that involve any hike a biking.
