make half sizes ffs

fit issues


I'm sorry to hear that the shoes didn't fit you correctly and that we do not offer half sizes, This is due to a decision made by B'TWIN to only offer full sizes, Your feedback will passed on to product managers in order to notify them that there are now more people looking for half sizes. 

In my experience you could either try a size larger or smaller, we would be more than happy to help with this as you have up to 365 days to exchange. 

Fantastic shoes!

These shoes were given a very good review in a cycling magazine, so I bought a pair. They are really comfortable, stiff and well made. Never had any issues with foot comfort. Mine are a bit scuffed after many trouble free miles and I just wish I could buy another pair when they do finally wear out!

Great Shoe

Been using for about a year now done about 7000km. Great power transfer from rigid sole. The finish marks easily but performance more important than appearance. The fastenings make it really easy to put shoe covers on as well. Best shoe I have used at this price.

Excellent product

Excellent road shoe very comfortable with a very stiff carbon sole

Poor quality manufacturing

Bought these from warrington 6 months ago, nice comfortable shoe but one of the circular fasteners has detached on sunday and lost on a ride so now unusable, I have lost receipt so decathlon unwilling to fix or replace, £80 thrown away. Previous shoes lasted 4 years

Great, the smart shopper’s choice

By far the best value shoe on the market. I tried most of the big brands but these were the most comfortable. To get two Boa-like rotary clips for tension adjustment you’d normally pay double this. They fit my (narrow) feet superbly, no slippage whatsoever, far better than any big brand. Stiff sole gives total power transfer. They vent well but not excessively - I wore these in winter without overshoes, and in hot weather too.

Good shoes but impossible to find spares!

I bought these shoes just over 1 year ago and absolute loved the stiffness and power transfer. I can also agree that they are good for summer rides as good ventilation kept my feet nice and cool. The build quality is okay, did scratch and scuff badly. However, one of the straps broke just over a month ago and I haven't been able to find any spares for less that £35, which is almost half the price of the shoe. It would be great if Decathlon could provide spares or information on where to replace these straps. Enjoyable at first but disappointed I can't repair them. If this changed I would readily recommend them.

Very comfortable so far

Great shoes but haven't lasted :-(

I liked these shoes so much I bought two pairs! They are light, stiff and great for power transmission to the bike. They are as good as much more expensive big brand shoes. My only problem is that after wearing them for less than a year, one of the dials has failed. Hopefully, I can get this sorted.

Super good Value Super Quality

Rode about 300km in these now and they feel great, fit well, with lots of adjustments. I also feel great about not paying a silly high price that other cycling shoes providers charge for very similar or lower spec shoes.

great v comfy and lightweight g price

wish there was a external heal loop to tie elastics to bike frame for my triathlons - so the shoes can stay level in competitions transitions.

I bought these shoes to give additional visibility on my daily commute, they look good too, I love the individual tensions and quick release twists.
