I bought a pair of Clarks Trigenic sandals at Sandton City in Johannesburg. The shop assistant was not particularly knowledgeable or helpful with regard to size and fit. The shoes (width D) were too wide for my narrow feet, but I thought I could shorten the fabric strap. Turns out it's almost impossible to achieve this. I have cut the fabric strap, so cannot return the shoes, and they are unusable. An expensive mistake. The colour range available in this shoe is limited to black and a pale pink. I didn't want black, so was restricted to the pale pink. A khaki or brown option would be more practical for me.
