After a year of use, I'm seriously impressed with these shoes!
I have wide feet with narrow heels (yeah, like a duck) and have always had a hard time finding comfortable cycling shoes. After being pretty happy with other Lake shoes, I did some research on their various lasts and as it turns out, the "Competition" last used in the CX241 is shaped more like my feet. They also provide actual measurements for all sizes and lasts on their website (https://lakecycling.com/pages/sizing-charts), so you can compare tracings of your feet to them to get an accurate fit. I didn't even have to go with their wide option to get a near-perfect fit. The heels are heat-moldable and I could probably perfect the fit by molding them, but I haven't yet.
They were very comfortable right out of the box and were broken in as much as necessary after a couple of rides. Even the somewhat skimpy-looking insoles work quite well. The uppers are an interesting combination of a perforated foam and mesh inner liner, with fabric-backed, perforated leather panels that over-wrap the liner and provide the closure system. There are openings in the leather at common pressure points, such as the base of the large and small toes, which is absolutely brilliant!
This construction allows the shoe to mold to your foot readily and hold it securely without having to be overly tight. It’s also quite airy and cool, although I did have to make one minor modification to improve airflow. The fabric on the inside of the leather panels is not perforated, so I poked an awl through the vent holes in the leather to open holes in the fabric.
An interesting by-product of this multi-layer, foam/mesh liner construction is that once you put covers over the shoes, they trap air really well and are actually quite warm. It also allows the shoes to expand to accommodate thicker socks without creating any blood flow restrictions. My feet have been perfectly comfortable down to 40 degrees F with shoe covers and medium weight wool socks. I guess I’ll save my winter shoes (which are also Lakes) for colder temps.
UPDATE: I delayed molding the heels until recently, when I purchased the matching MX241 for off-road use. I used a different method than Lake recommends. I heated a large bowl of water to 200 degrees, removed the insole, put the heel of the shoe in a thin plastic bag, tucked the plastic into the heel, then submerged the heel in the water for 90 seconds. It became very pliable and after removing the bag and reinserting the insole, it was easy to mold for a perfect fit. It took more time to heat the water than to mold the four shoes and it's definitely worth doing.
