From guitars to moustaches and from keyboards to jogger pants, the doodles on the special player edition of the ECCO M GOLF BIOM® H4 showcase the personality, style and interests of fun-loving Erik van Rooyen. Those drawings can be found on the vibrant outsole, which fades from blue to red, as well as on the colourful, blue-to-red insole of a shoe that also has the ECCO ambassador's logo, and a print on the puller which is designed to look like guitar strings. The special edition has all the same technologies as the regular ECCO M GOLF BIOM® H4, including BIOM® NATURAL MOTION®, an ECCO MTN GRIP outsole and 100% GORE-TEX waterproof protection.
