Take radius 24. Thats what evo adviced

Most of the time it is, but it takes 6 weeksw delivery time at this moment

It will fit most of all inline skates and ice speed skates. Rollerblades and urbans don't fit very well.

You can check here the size chart

At this moment ther is no sizing tabel, you can use the viking sizaing chart and add one size. so if you have Viking size 43, you need a 44 of Groothuis

The Bont Crono is even like the other Bont skate boots a bit heat moldable

It is both, 165mm and 195mm across mounting.
