I`ve got a pair of normal Gazelles, they look fantastic but are possibly the most uncomfortable trainers I`ve ever had, to low in the collar & tight round the heel. They cane my feet, even when driving, never mind walking.
I`ve also got a pair of Samba, possibly the most comfortable trainers I`ve ever had & they have a very similar look to the gazelles you`ve been looking at.
I`ve also got a pair of Samba Supa as well, bit harsh under the heels when walking round town for a long period but alright for cutting about in, but the fit is excellent & they look fantastic.
Check out the Adidas website, some nice shoes on there.
