Why We Like The CX238 Cycling Shoe

Lake evolves the CX237 to the new CX238 with updates to improve the longevity and performance of this long-time favorite road racing shoe. The Competition last is shaped for better fit and comfort during hard efforts, with a slimmer heel and wider forefoot to allow for foot expansion under pressure. Supporting it all is Lake’s Race carbon fiber sole, providing the stiffness we need for better power transfer and durability. A panel at the heel and a rubber bumper at the toe protect from prematurely wearing out the full-grain leather upper, which has mesh panels and venting to improve cooling.

  • A premium road race shoe
  • Race Carbon sole efficiently transfers power
  • CX Competition last provides a secure fit and wider forefoot to relieve pressure
  • Full-grain leather is supple and comfortable
  • Mesh paneling and vents enhance airflow and cooling
  • Dual BOA dials provide precise, secure closure
  • Compatible with 3-hole road cleats

How to Measure:
Take your foot measurement In a standing position while wearing your cycling socks.
Step 1: Trace your foot onto a sheet of paper.
After you trace your foot take a ruler and make a line to mark the furthest point on all four sides.
Step 2: Length measurement.
Use a millimeter ruler to get the measurement of the longest distance from heel to longest toe (first or second toe).
Step 3: Width measurement.
Use a millimeter ruler to get the measurement of the widest distance of foot from side to side.
Step 4: Repeat steps for other foot as your feet may be different sizes.
Typically you will want shoes that accommodate your largest foot the most comfortably.
Add 5mm to your actual length measurement to get recommended size.
Please Note: for accurate measurement please obtain a 3 digit millimeter measurement. Accurate measurements cannot be obtained from only 2 digits.

Best shoe I’ve owned

I've used it once or twice and have initial impressions
True to size

The first time I put them on, even before I attached the cleats, I knew they were keepers. I had not planned to spend that much money. They have a large toe box which is just what I need while the upper softly hugs your foot. The arch is nice These are my first shoes with carbon soles. What a difference. Pedaling is like being on an elliptical like you’re whole foot is applying pressure. Lake has won me over..

Worthy Successor to the CX237

After trying on, buying, and selling countless shoes I finally found my perfect fit: the CX237. I rode the CX237 for a year before the inner lining tore and I had them replaced with the CX238. I've been riding the CX238 now for a year and three months. For those of us with wonky feet, the wonderful fit of the CX237 carries over to the CX238 (I have duck feet). The inner lining is significantly more durable than the CX237. The tongue and ventilation are a bit better. The cleat alignment marks are still crooked. The BOAs are still wonderful. With approximately 7,500 miles and 360 hours, they are still going. My riding has been 70% outside in moderate to high heat and 50-90% humidity and 30% on an indoor trainer. By now the upper lip of the tongue has lost its pliability (not nearly as badly as the CX237) and the outer leather, near the inner ball of my foot, has started to tear. I have done nothing to care for them, though. Perhaps proactive leather conditioner would turn these into 15,000+ mile shoes?

Finally a shoe that fits

I own two pairs of Shimanos, both sized 43. I was looking to retire a pair and went on the search to upgrade into a nicer shoe. Since both shoes fit great and my difficulty in finding shoes that fit, I decided to stick with Shimano. (I have flat, low volume feet w/ a low instep and narrow heels - think duck feet.) I decided to try the RC9s on sale in the same size. Disappointingly, the fit was off. Great construction as expected and length was perfect, but the toe box was simply too narrow. I didn't try the wide because based on experience, I find wide versions mean more volume, which never works for me. Researched and learned that the Lake CX238 has a wider last than most in their standard fit. Spoke to a Competitive Cyclist associate (sorry, forgot his name) who confirmed this and so decided to try them. My foot landed between the 42.5 and 43 according to Lake's measurements and chart, so ordered both. The 43 felt best; the 42.5 was a tad bit narrow. Overall, great construction like the RC9, but feel the CX 238 is more durable; very similar to Sidi's. Also, I prefer the quality natural leather construction which I expect will break in well over time and prove more breathable. I tried them out on a 30 mile ride and they felt great. Pedaling felt efficient and comfortable. I found the heel cup slightly wider than my Shimanos, but they posed no issues while riding. If needed, I know I'll be able to fine tune this with a bit of heat molding. I can see why these shoes are popular. Obviously, I know fit is very personal, but these may be worth a shot. However, I'd recommend consulting Lake's website and following their sizing and measurement chart and ordering a few in your size range to get the best fit (make sure to follow Lake's instruction by adding 5 mm to your foot length when measuring). As a final note, the micro-adjustments allowed by the IP1-S BOA dials are money.

I have not ridden with these yet. I used the chart, and ordered what I thought was the correct size, 44.5 (same as my current Shimanos). They were too small. Have returned them for 45s, and hoping they fit. But according to that chart someone with an 11.5 shoe should use a 45. no way my feet are that big. Update: The 45s arrived and they are a perfect fit. After one 35 mile ride it's easy to tell how good these shoes are. Comfortable, and a really stiff sole. Also have good arch support and a comfortable heel cup. Excellent shoes.

I really like this shoe. I have bought lots of different shoes looking for the perfect fit and look, This is the first shoe that is comfortable and where I don’t get any slip in my heal. I have a high instep and narrow heal. To accommodate my instep I normally have to buy an 11 in shoes and sneaker even though my foot measures a 10/10.5. This has been an issue in cycling shoes because the extra length means lots of heal slippage. If I crank if down to prevent that, my arch gets crushed. With Lake I can a nice fit, no heal slippage and no pain. But, the Lake is not the sleekest looking shoe on the market. But I will trade performance over style any day. Lake also has a great sizing protocol on their website. Follow it, it works!

Shoe fit true to size. Wider and lighter than my Sidi shoes . Very comfortable after my first few rides. I hope they last as long as my Sidi’s did . Ride about 10,000 miles per year.
