The ankle roll is presently under development but it is likely to be a cone that tapers from 10cm to 15cm over a length of about 60cm made from a material that will allow some compression. This is in-line with the WFTF proposal. The development in England is being led by Andy Calpin and in Spain by Jesus Sangroniz.
If you're doing your own personal one, there's obviously no need to make one 60cm long!
