The Yonex Sonicage 3 is the comfort play of the Yonex footwear family.  The shoe comes in two variants.  The standard, presented here, fits a little narrower than the rest of the Yonex footwear offerings.  This fits close to a C width foot and is comparable to the ASICS Solution Speed FF2.  The wide version of this shoe fits wider than the rest of the Yonex footwear offerings and is closer to an E width.  Both models of the Sonicage 3 provide ample cushion and support for the avid tennis player.  If you are an aggressive tournament player, you might be better off with the Yonex FusionRev 4 or the Yonex Eclipsion 4.
