Unsure whether to blame NS Watersports? Ordered a pair of Adidas sailing trainers size 8, they arrived but seemed very small. Stupidly I was going out and wore them (so they cannot now be returned to ask for the next size up). I wonder if they are marked the wrong size as the bottom of the shoe looks smaller than other size 8 shoes. Be warned and order a size larger if thinking about buying Adidas Terrex 255 HEAT.RDY trainers. I feel that I have wasted £75 that I could not afford to waste in these current times. Check before you use goods. Company were good to offer me half my money back, the action was appreciated.
