currently using SHB98 and 99. Bought the 90 to replace my SHB98 which is getting old. Bought at Queensway for $90. Impressions of SHB90: (1) Insole is the lower-end type and not the nicer type found in the 99. The 99 insole is very nice. (2) Better shape for my foot vs SHB98, not as long and narrow. (3) 99 cushioning and support is still better but 90 is more maneuverable like the 98. (4) I would call the 90 a slightly improved 98. I still prefer 99 as support and cushioning are more important to an old guy like me where the cost of a specialist consultation with a foot doctor can buy one pair of shoes....
when you choose the color, SHB 99MX red/white this style very like for comments, ladies sky blue/white with very interesting
