With the keenest weight watchers now counting grams on their kit as well as bikes, more dedicated lightweight products can be found in new ranges.

The adidas Ultra SL is a range-topping race shoe, weighing a scant 290g (size 8.5). Pretty much mandatory at this level is a full carbon sole; adidas uses its Prolite, low-profile, low weight and super-stiff design.

A mostly mesh upper and smaller micro ratchets save more weight, and two Velcro ?Fast Straps? keep the fitting snug, over an asymmetrical tongue which prevents material rucking and discomfort under the fastenings.

Each pair includes a shoe bag­ ? useful, but not the main reason for spending £199.00
