Extremely narrow + 1/2 " shorter than the latest GTX model
Much smaller and lighter than the previous Salomon GTX. Please increase the size by at least 1/2 when ordering. I have a normal average foot of 11. It's somewhere in the 10's. Very tight at the ball of the foot from left to right.
Pros
Can be worn with or without socks
Cons
They may not be suitable for people with calluses or calluses.
