Excellent service from Sigmasport, super quick delivery to mainland Scotland. Shoes are so nice and so comfy, they have quite a lot of ventilation. I was a bit doubtful of which size to go for and I ended up going for EU43.5 280mm which they fit perfect. For reference only my both feet measure 275mm length, 100mm wide one and 102mm the other. I also have a pair of Giro Empires size UK9.5 EU44 US10.5 CM28 and I would say they fit pretty much the same. I hope this may help someone that is also doubtful about sizing.

Fizik R3 Transiro Triathlon Shoes
Fizik's R3 Transiro Triathlon Shoes will help you chase your best race performances. The breathable mesh upper will keep your feet supported and at a comfortable temperature, and combined with the stiff carbon outsole helps transfer your watts efficiently through the pedals. Perfect for triathlons, the Powerstrap and Boa dial first ensure quick closure, and then allow micro-adjustments to fine-tune the fit. The Infinito textile webbing system builds on this by evenly distributing pressure and eliminating hotspots so you can perform in complete comfort.

Sizing note: Fizik shoes are built with a performance fit: true to size in length but with a narrow, low-volume toe box. Do not size up — it won't solve a width issue. If you have a wider or higher-volume foot, choose the Wide Fit version. If you're unsure whether Fizik suits your foot shape, check our size and fit guide before ordering.
Accurate sizing guidance can be gained by measuring the length of your feet from the back of the heels to the tip of the big toe. This measurement corresponds to the "Foot Length" column in our size chart.

They open very wide and therefore allow for easy entry when wanting a fast transition. The shoe is also extremely comfortable as their made with a very smoot and soft material. When riding with the fizik Transiro I also feel I generate more power through my pedaling, I really do love this shoe and highly recommend them for anyone contemplating whether to get them. Thanks Sigma for a great shoe

About Fizik
Where the rider meets the bike.
Fizik was founded in Northern Italy with the conviction that the three points of contact between rider and bike — saddle, shoes, handlebar tape — deserve the same engineering focus as the bike itself. Every product is engineered around the rider's body to make the long ride feel shorter.
Fizik's saddle range is organised around the Spine Concept — Bull, Chameleon, Snake — matching saddle shape to rider flexibility. The result is a comfort claim backed by anatomy rather than marketing.
