I was very surprised at how different the fit was versus the Kinvara 4.  My 4's have a semi-minimalist feel... nice, light, simple fit without much padding around the top or sides.  I love them and had expected the same with the 6's.  Instead, the 6's feel like classic &#34;sneakers.&#34;  They are too tight and too heavily padded.  It's a lot of shoe.  Never in 25 years of buying saconys have I ever returned a pair of shoes, let alone without even walking in them.  If it's a semi-minimalist feel you are looking for, something has really changed in the Kinvara design, and the 6's are not for you.
