Go down half a size from your true size (ie I am a true size 9.5, so I buy my V6s in a size 9)
The V6 comes in wider and narrower widths in its core classic colorways (Grey, Navy, and Black) as well as a limited selection of other widths in other more mass-produced GRs.
Comfort Factor Ratings:
Cushioning (Softness): 8/10
Stability (Firmness): 5/10
Cushioning to Stability Ratio: 8:5
Midsole Shape (Support): 8/10
The 990v6 has noticeably more softness and a more supportive midsole shape than its predecessors. The inclusion of FuelCell foam makes the shoe softer and more responsive. The foam rebounds your feet, pushing you forward. This is enhanced further with the combination of ENCAP and FuelCell in the heel area. The stability of ENCAP in the heel helps push your feet forward. The V6 is a really impressive performance running shoe that also looks dope for lifestyle wear!
