You will be amazed at the quality SIDI put into a youth boot :thumb: He had the Alpinestar Tech 6 before, and they never really broke in all that well. When he got the SIDI boots, instead of taking off the boots (like he did with his Alps) inbetween motos to play with the other kids. He left them on, and could run like crazy. I do believe they have the best flex in the ankle (I wear them myself) and are well worth the money for a young one. He wore them for 1 season and the held up very well.
