I could give yo a tip,which you may find interesting.
Asics makes Butterfly's shoes,and thay also make their own with their brand.
Their 1's cost a fraction of butterfly's,even though they are more or less the same.
For me,its Ma Long or Jun Mizutani(cant decide which,but my choice is leaning more towards ma long)
Great consistency,and they try their best in every competition they play.
