Step 3: The all important teeth
TAKE IT SLOOOOOW.
First mark out were you want your teeth
there are really no standards to where and how high but a minimum of 4 cm high is recommended. (I have seen some that are as high as 17 cm !!!)
Use a chisel (i think that its the right name) and a hammer to slowly remove the wood.
Make sure you dont hurt the teeths.
Do this on both shoes :P
OBS the front shall be a bit longer than the back. for more easy walking
