Why your credicard declines?
Credit card declines happen when a bank refuses a payment. Two main types are soft declines, which are temporary and may be retried, and hard declines, which are final due to reasons like fraud or insufficient funds.

Common decline codes include:

  • Code 05: Bank's unexplained refusal.
  • Code 14: Wrong card number entered.
  • Code 41: Card reported lost.
  • Code 43: Card reported stolen.
  • Code 51: Not enough funds.
  • Code 54: Card expired.
  • Code 63: Incorrect CVC.
  • Code 65: Credit limit exceeded.

Why cards get declined:

  • Insufficient funds or reached credit limit.
  • Unverified customers. To counter this, use 3D Secure 2.0 (3DS2) for better authentication.
  • Suspicious activities like unusual buying patterns can trigger fraud alerts.
  • Using a canceled or expired card, a common issue for recurring payments.
  • Challenges in cross-border transactions due to different banking systems and regulations.
  • Incorrect payment details like a mismatched billing address.

3D secure 2.0

To minimize declines, understand these causes and consider using advanced authentication methods like 3D Secure 2.0

3DS2 is the umbrella name for each of the Card Schemes’ branded online payment authentication solutions: Visa Secure, Mastercard Identity Check, American Express Safekey, J/Secure for JCB and ProtectBuy for Discover and Diners International. It is an authentication protocol that was designed to reduce fraud, increase customer security and reduce merchant liability to chargebacks.

ChatGPT3D Secure 2.0 (3DS2) is an advanced security protocol for online card transactions. It offers a smoother user experience than its predecessor, often authenticating transactions in the background. Utilizing risk-based authentication, 3DS2 evaluates over 100 data points to determine the risk level of each transaction, allowing low-risk payments to process with minimal user intervention. This approach significantly enhances fraud protection. 3DS2 complies with regulations like the EU’s PSD2, mandating Strong Customer Authentication. It supports a range of devices and modern methods like biometric authentication, aligning enhanced security with user convenience and regulatory compliance.

Size Charts & Fit
Your Perfect Cádomotus Boot Size

How do I find the right shoe size?

Boot sizing, molding, and fitting

Go directly to size tables:

Maattabel Insole Resizers - Maattabel Rookie One & Two - Maattabel SR2 & NS2 - Maattabel Ci1, Mi2, Versatile-3, Agility-3 - Maattabel Ci1 iD boots - Maattabel voor Balance & Pressure schaatsen - Maattabel Triathlon Chronos & Worldcup T2

Tips in advance

  • Measure both feet from your heel to your toes (follow the instructions in the illustration below). Some people have one foot slightly larger than the other. Choose the size that fits the larger of the two.
  • Consider the socks or tights you’ll wear most often with your boots. For thicker socks, you may want to order boots ½ size larger than you normally wear.
  • Measure your feet in the afternoon when feet tend to be their largest.
  • Add 3mm to your measurement before looking for the right size in the table
  • We advise ordering a ½ size larger if you have extra wide feet.
  • Inline boots should offer a couple of millimeters of extra space at the toes.


  1. Thin pen or ballpoint
  2. 1x A4 paper
  3. Ruler (note from 46 you will need a ruler larger than 30cm or a tape measure)

Measure your feet

  1. Place the A4 paper on the ground with the short side against the wall
  2. Put the first foot on the paper with your heel against the wall
  3. Put a book against the longest toe (usually your big toe)
  4. Now gently remove your foot without moving the book
  5. Now put a line along the book and put a letter R or L by the line
  6. Now repeat steps 2 to 5 with your other foot.
  7. Now measure the length of both stripes and choose the longest result
  8. Add 2-3mm to your measurement before looking for the right size in the table
  9. Add another 2mm to the result for thick socks if necessary
  10. Scroll further down for the right size chart and find the measurement in mm in the right column then you will find the size of the skates in the left column.

How to determine your foot length

Extra wide feet

Standard width

All Cádomotus boots are built on standard fitting lasts. Standard shoe width means an F fitting for men and children and a D for women. The width can be adjusted, broadened, or narrowed, by molding the boots.

One size bigger

If you have wider feet we advise you to buy one size bigger. This always works out fine and does not cause any problems in length.

Width adjustment

Cádomotus boots are heat-moldable to fit perfectly to your feet. The part of the boot that responds the best to molding is the ankle area, which can be widened, narrowed, or even totally reshaped almost without any limitations.

Molding the heel pocket can be sufficient but will have limited effects since the bottom of the shell is extremely rigid and solid, so this part will not deform. However, you can usually widen or narrow the heel part up to 1-2 mm. As for the toe box area and the medial or lateral side of the boot, they can be enlarged up to 2-3 mm.


Sizing charts for the right shoe size

The chart below details the dimensions of all boots and shoes. The width of each boot can be adjusted to fit your feet if they are wider or narrower than the European standard F fitting. In order to do so, please continue reading our heat molding instructions.

Heat molding instructions

How to mold skate boots?

Oven, maximum 80 degrees celsius, 15 minutes

Molding your boots in the oven has several advantages, such as the continuous and controlled overall heating of the boot. If the boots require to be molded in different places (heel and ankle), the oven is your best choice.

However, you should also be aware that there are also some downsides to heating your skating boots in the oven. The parts that you do not necessarily want to mold are being heated too, and you take the risk of deforming these parts unintentionally, for example the carbon sole section. If you apply load on the sole, the carbon could bend or twist and mounting blocks may dealign. During cooling down after heating, do not wait standing up with the boots on your feet, always sit on a chair to avoid that problem.

Another risk of molding your skating boots in the oven is that the glue may not resist the heat and the upper of the boot could detach or misalign from the carbon shell. We strongly recommend not to tighten your laces too much and not to fasten your buckle to avoid damaging your strap. It would be better to use a heat gun to mold the boot around your feet. This should be done at one of the Cádomotus Pro-dealer shops, or at the Cádomotus booth during an event. The 2022 list of events where Cádomotus will be present will be published soon.


Oven for heat molding

  • Continuous and even heating, inside and outside the whole boot
  • Controlled temperature
  • Glue and leather become soft


  • Uncareful handing may cause misalignment of the mount blocks or deformation of sections that you do not want to re-shape


Heat gun boot boot molding


  • Local heating on the desired spot only.
  • Other parts of the boot remain in perfect condition.


  • Risk of burning stitches or leather when keeping heat gun too close to the boot.


Heat gun

Heating with the heat gun has one main pro: it only heats the area that you want to mold, and nothing else! This means you do not have to worry about inadvertently deforming or damaging other parts of the boot. In general, your boot remains in better condition and will last you longer.

Therefore, molding with the heatgun is a better option when you have small pressure points in your boot, like on the inside or outside of your ankle, or at the navicular bone. You can use a ball-and-ring-stretcher to adjust a specific area.

The downside of using a heat gun is that the molding temperature is less easy to control. If you keep the gun too close to the boot, you can easily burn the stitches or the leather. We advise you to move the gun slightly on and around the spot that you want to mold. As soon as the spot becomes soft, you may mold the shell with your hands (wearing gloves) or with a pair of cobbler pliers.

If you need to adjust only one specific area or one spot, then the heat gun is your best choice for molding. When the mid foot and/or toe box area, or the whole counter section, needs molding, then we advise to use the oven.

Please note that every time you heat up the boot, it has a impact on its durability.

How to replace the disc dial unit on your shoes

The Cadomotus cycling shoes are equipped with Freelock MPK dials. These dials are known for their fast and secure tightening. Even more important is that they do not lose tension during your ride.

After a crash, for example, it may have happened that the dial got damaged and therefore needs to be replaced. This is fairly easy and quickly done, it doesn’t require any special tooling other than a small screwdriver. In this video we explain how to remove the Freelock MPK Dials.

Please note that there are two types of dials: clockwise closingand counter-clockwise closing, both indicated on the bottom with an RH sign for right-hand closing (clockwise) and LH for left-hand closing (counter-clockwise).

The replacement of the dial in a few steps.

  1. Use a small screwdriver to release the dial
  2. Pull out the wire lace all up to the end
  3. Cut off bot ends of the wire lace
  4. Take the new dial
  5. Rotate the internal mechanism to align both triangular arrows
  6. Stick both ends of the wire cable through the dial, the ends should come out at the opposite side
  7. Make knobs in both cable ends and cut the ends if longer than 5mm
  8. Pull the knobs into the mechanism, pull firmly to settle the knobs into the mechanism
  9. Click the dial into its seat on top of the tongue
