If you have bought a pair of Hoka running shoes recently, you may have seen some numbers and letters on the inside of the midsole. Below is a list of what they mean.
|S||The ‘spring’ of the shoe. How far off the ground in millimetres the toe and heel sections are|
|V||The volume of the midsole cushion in cm³ (cubic centimetres)|
|W||The weight of the shoe in grams|
|C||The carbon plate version number|
And below are some shoe examples.
|Clifton Edge||36 x 20||734||246|
|Torrent 2||33 x 16||395||270|
|Challenger 6||37 x 30||641||276|
|Mach 4||39 x 25||642||238|
|Clifton 8||34 x 22||655||250|
|Rincon 3||38 x 24||603||215|
|Kawana||35 x 32||712||288|
|Speedgoat 5||35 x 21||651||284|
|Arahi 6||33 x 23||667||269|
|Zinal||32 x 19||490||242|
|Stinson 6||42 x 33||809||332|
|Cielo X LD||12 x 45||211||104|
|Cielo X MD||14 x 49||173||126|
It’s worth emphasising that the ‘spring’ measurement is the curvature of the shoe – not the heel-to-toe drop (normally 4-5mm). Hokas have a signature rocker feel to them, hence why something like the Mach 4 has a difference of 14mm from back to front.
With regards to the carbon plate numbers, these currently range from C001 to C003. Below is a list of what plate is in each shoe. And yes, the stats are the same for both Carbon X shoes!
|Carbon X 2||41 x 36||728||C001|
|Carbon X 3||41 x 36||728||C001|
|Rocket X||40 x 15||612||C001|
|Bondi X||35 x 30||884||C002|
|Tecton X||36 x 26||701||C003|
How is this information useful? Well the more you know, the more informed a decision you can make about which shoe is best for you.
This only really applies if you are browsing for shoes in an actual shop of course. Remember those?
