Go down half a size. (ie: I am a true size 9.5 so I buy my 991v2s in a size 9)
The 991 v2 does NOT come in wider or narrower widths.
Comfort Factor Ratings:
Cushioning (Softness): 7/10
Stability (Firmness): 5/10
Cushioning to Stability Ratio: 7:5
Midsole Shape (Foot support): 6/10
The 991v2 adds FuelCell into the midsole, providing it with an overall softer feel on feet. The midsole shape is flatter than the original 991, so it isn't as supportive. The 991v2 is a pretty comfortable lifestyle shoe, especially with the addition of FuelCell.Â
