Read My Sports Gadget Recommendations.
Here’s my most recent GPS watch guide here, and cycling GPS computers here. Plus there are smart trainers here, all in these guides cover almost every category of sports gadgets out there. Looking for the equipment I use day-to-day? I also just put together my complete ‘Gear I Use’ equipment list, from swim to bike to run and everything in between (plus a few extra things). And to compliment that, here’s The Girl’s (my wife’s) list. Enjoy, and thanks for stopping by!

Have some fun in the travel section.
I travel a fair bit, both for work and for fun. Here’s a bunch of random trip reports and daily trip-logs that I’ve put together and posted. I’ve sorted it all by world geography, in an attempt to make it easy to figure out where I’ve been.

My Photography Gear: The Cameras/Drones/Action Cams I Use Daily
The most common question I receive outside of the “what’s the best GPS watch for me” variant, are photography-esq based. So in efforts to combat the amount of emails I need to sort through on a daily basis, I’ve complied this “My Photography Gear” post for your curious minds (including drones & action cams!)! It’s a nice break from the day-to-day sports-tech talk, and I hope you get something out of it!

The Swim/Bike/Run Gear I Use List
Many readers stumble into my website in search of information on the latest and greatest sports tech products. But at the end of the day, you might just be wondering “What does Ray use when not testing new products?”. So here is the most up to date list of products I like and fit the bill for me and my training needs best! DC Rainmaker 2023 swim, bike, run, and general gear list. But wait, are you a female and feel like these things might not apply to you? If that’s the case (but certainly not saying my choices aren’t good for women), and you just want to see a different gear junkies “picks”, check out The Girl’s Gear Guide too.
From the third ‘graph, you quote the shoe price as “The good news is that it works with all of their cycling shoes, from their 50EUR ones up to their 350EUR editions.” However, later, you note the minimum is €250. My reading of the site seems to point to the higher figure.
The 50EUR-350EUR figure is for the shoe itself, without the power meter. Then you add the 200EUR for the power meter, hence where I was getting 250EUR from.
Where do you see something else?
No, as you state it, the is math correct. I was confused about the wording, apparently.
And on a side note, if this product comes to market near the projected price (and date), it’d fly off the shelves. Being able to adapt this to practically any pedal system irrespective of components (crank-, pedal-, and hub-based systems) is truly a game changer. My ideal use for these would be on a gym’s spin bike when carrying pedals, wrenches, etc, is less than ideal. Assuming my SPD three-hole conversion plate would work on this, this method is would easy to implement.
The Bike Radar report of pricing for compatible shoes seems to be slightly higher:
“The Luck Potentiometer (power meter) can be bolted onto any high-end Luck shoe — road or mountain — according to Luck director Juan José Pascual. There are about 16 models for between €200 and €300 that can use the meter. US and UK pricing was not available.”
Indicating maybe that the system isn’t compatible with their lower end shoes (unless this has changed since that article).
Would put the pricing for left only at €400 – €500.
Yeah, we actually had a fairly in-depth discussion about it being compatible with anything (it’s what led to the photo of him holding up both shoes at once).
But it also wouldn’t surprise me if there were still language issues there.
So, if I’m reading this right I would be able to buy the Luck shoes and get the left only power meter to start and upgrade pretty easily to left/right power at a later date. Is that correct?
If so, I think I’ll be the second person in line, right behind you.
when battery runs out, “My luck just ran out” :P
I have some doubts concerning durability… I mean, my usual cycling shoes are pretty beaten up after 2 years and more than a few thousand kilometers. I am not sure those electronics can hold up to that protected by – what looks like – a thin layer of (albeit re-enforced) plastic.
What are you doing g to your shoes?
My S-works from 2006 are still in respectable shape.
(to be fair, minimal riding between 2013-2016 and several tri shoe rides a year but still…)
I agree with you to a certain extent, however, at these price points (and the only direction to go is down from here), a life expectancy at the low end of 2-3 years would not be bad at all.
There’s a lot of durable electronics that are protected behind a reinforced plastic. also, what if you could transfer the plate into a new pair of shoes
Please let this really happen!! It’s the holy grail of power meters. I already have a PM on every bike I own and I’d STILL go out and buy this if only to have power when going to spin classes!
Any cleat type or any 3 bolt road cleat. I’m married to 2 bolt SPD. I’m older and a little too unsteady to eat or drink while riding, especially on urban roads and I like that cleat and shoe for all the stops. So far only Stages and Power2Max seem to fit my, er, well, not need but definitely want.
Ditto on the two bold SPD primarily because of the multi angle quick release and alternative shaft length needed after having an ankle reconstructed with metal screws.
Still, I’d put the S-Works into the closet and purchase a new set of shoes at this price point. Even better if I could swap between road and mountain bike shoes.

Looks like something i’ll also have to keep a close eye on. I’m also on two bolt SPD all the way around: mtb, road, bmx and indoor ergometer. At the moment i only have two pair of shoes :-)
As always said… pretty much anyone can make a powermeter to the 90%-95% point…thats when it gets difficult.
Remember it took Garmin 2.5 years after purchasing Metrigear and then still had problems even with all their IT nerds working flat out…
This could be really a revolution! You choose the crankset, the pedals and the setup that you want.. No switch between bikes needed, you could also use it on rental bikes if you travel. If it will be precise I will buy for sure… When will see a real test?
I’m curious as to how they can accurately distinguish tangential and radial forces. Looks tricky to measure heel scraping type movements or to reliably work out the angle of the shoe in relation to where it is in the pedal stroke.
I’m guessing that it has an accelerometer (like pedal-based systems) which would detect where in the pedal stroke the shoe is. But I agree that seems like it could be a major source of error. Especially since a shoe isn’t necessarily at a known angle at any given point. With a pedal-based system, you know that the strain gauges in the spindle are fixed to the reference frame of the cranks. But the shoe could be at any angle, likely pretty close to horizontal on the downstroke and slightly toe-down on the upstroke. But again I’m not sure how you accurately measure that to take it into account.
Just adding to the comment. Keith Hack recently posted a blog entry due to Brim Brothers bowing out.

Is this the same company? Looks like they have been working on this for a number of years

So you can buy a set of shoes and get either left, right or both meters attached right?
What happens when you only go for the one shoe option in terms of shoe height? surely one shoe cleat will be higher than the other or do they give you a plastic plate to just fill in the other shoe that doesn’t have the power meter?
Otherwise i can see a lot of people hobbling about like John Wayne at the coffee stop.
I’m interested to see how the increased stack height works out. I know there are spacers that fitters can use to fix imbalances, wonder if it will impact action on Look/SPD-SL pedals.
I’d also be a little worried about durability to some degree, being on the bottom of the shoe. I know that my outsole gets pretty dirty and beat up over time on my shoes…
I would love this. But the P1 still looks the best in terms of going anywhere
Just so you are all aware this looks like a piezo electric sensor. No strain gauge. They work on changing resistance as pressure is applied through the ball of the foot which can then be converted to how much down force is being applied through that area of the foot. It will not generally detect upstroke ‘pull’. There are similar products measuring insole forces for gait analysis ie Moticon insoles. The sensor are quite cheap, are guaranteed for ?100 000 000 actuations (300 hours of cadence of 90) but often need ‘calibrating readings’, have hysteresis issues, temperature fluctuations. Aka similar problems to strain gauges.
I bought a raspberry pi & a collection of sensor for $100 in a vain thought I could do a Hackaday type DIY power meter. Lack of time & intellect defeated me early on in this.
Any update on availability? I’m firmly sitting in the ‘I would buy this’ camp. Seems pointless contemplating anything else with this on the horizon.
I haven’t heard anything. And honestly, I really wouldn’t expect anything. They’re just nowhere near where they think they are.
Many thanks for the swift reply. I’m seriously thinking time to pull the trigger on a DFPM. Will trawel your reviews again. I really want something interchangeable or at least compatible with one of my current road setups (2014 Super Record and also don’t want a wheel based system, so I’m awkward)
Any more news on availability?
Have these guys been to any summits lately or updated their status? I’m in the market for new shoes and would be willing to hold off until next season – tho their website doesn’t give any details other than they aren’t available yet.
Hi Ray – The Luck shoe-based power meter seems like it’s got so much cool potential. Any word on whether they’re bringing them to market anytime soon? Thanks!
I’ve tried emailing luck about it and never got a response after 3 weeks…
