How various Five Ten models shoes fit
As for 5.10 bike shoes, all models are reported as true to size, but there are some peculiarities in the fit of individual models.
For instance, the Five Ten Freerider offers a roomy toebox but may require a break-in period due to the upper and sole stiffness. It also comes in a women’s-specific version that caters to a narrower footshape. As for the Sleuth, it has a more pointed toebox and stiffer upper material overall.
When it comes to climbing shoes from Five Ten, they are reported to run half-a-size to a full-size smaller than the other brands in that category. For these models, it is advisable to check information on the individual product pages. We collect users’ feedback from all over the internet for your convenience.
