Lee&Yang, Goyang, Korea ·

STUD-08 FG replacement sole seen from below and from the side, the sole used most often in our published resoling jobs

Which sole do people choose when they resole football boots? We counted every published job in our workshop's before-and-after galleries, mostly work from 2019 to 2021: 3,228 resoling jobs where the new sole number was recorded. More than half chose a turf sole, and the most common change of sole type was turning firm ground boots into turf shoes.

  • 56.1% chose a turf (TF) sole1,812 of 3,228 jobs. Firm ground (FG) came second with 779.
  • FG to turf: 1,087 jobsThe most common conversion, 34.1% of the 3,191 jobs where the original sole was recorded.
  • Same sole again: 1,086 jobsAlmost as many people simply replaced a worn sole with a new one of the same type.
  • Most used sole: No. 8 (firm ground)498 jobs, followed by No. 10 (485) and No. 9 (467), both cushioned turf soles.

Which sole types people chose

We grouped the 3,228 jobs by the type of the new sole.

  • 56.1% · Turf / futsal (TF)1,812 jobs

    Many short rubber studs. For futsal courts and short-pile turf.

  • 24.1% · Firm ground (FG)779 jobs

    Longer molded studs. For natural grass.

  • 12.4% · Artificial grass (AG)400 jobs

    Short, closely spaced studs. For long-pile artificial grass (3G and 4G). Includes 9 kids' soles.

  • 5.8% · Multi ground (MG)188 jobs

    Mixed stud lengths. For artificial grass and dirt pitches.

  • 1.3% · Indoor (IC)43 jobs

    Flat sole with no studs. For indoor wooden or sports floors.

  • 0.2% · Soft ground (SG)6 jobs

    Wet grass and soft mud, screw-in metal studs

Many football pitches in Korea are artificial turf or dirt rather than natural grass. Many of our customers bought boots made for natural grass and then had them changed to suit the pitch they actually play on. If you are not sure which sole fits your pitch, read FG, AG, MG, SG or futsal: which sole do you need.

The six soles we used most

We offer 19 numbered replacement soles. These six account for 67.8% of the jobs.

Count of published jobs that used each sole. Photos and sizes of all 19 soles are in our sole catalog.

From which sole to which

In 3,191 jobs the description also says which sole came off. These are the ten most common changes.

"Molded studs" means the job description did not say whether the original sole was FG, AG or MG.

We confirm from your photos whether a pair can take a turf sole. Most boots also need a new midsole, the layer between the sole and the insole, and when we fit a turf sole we can stitch a toe reinforcement. See futsal shoe resoling for how the conversion works, and our repair page for prices.

By brand

Turf soles came first for every brand with enough jobs to compare. Mizuno was the only brand where AG beat FG.

TF turf, FG firm ground, AG artificial grass, MG multi ground. Share of each brand's jobs with a recorded sole number (3,202 jobs across these four brands; 26 jobs were other brands). IC and SG are left out, so rows do not add up to 100%.
