# Do Shimano MTB shoes in half-sizes make a perceptible comfort difference?

My 10+ year old MTB shoes are finally dying. I'm looking for replacements.

My shoe size is usually 7 UK (42 EU) for the left foot and 7.5 UK (43) for the right. I see Shimano do European half sizes (under size guide). Some shoes are available in half sizes, others not.

Does anyone find that Shimano MTB shoes in EU half-sizes make a perceptible comfort difference compared to full sizes?

• There's really no way for someone to answer this with any level of utility; the value of half sizes is highly dependent on your feet and almost nobody will have enough time with the same shoe in the half size or non-half size to tell the difference. Enough people think they're good since they continue to make them. Get the shoes that fit you best. Commented Jan 16, 2018 at 0:21
• Do you buy your normal shoes in different sizes as well ?

• @batman: Good point about market demand, as long as they are reacting to demand and not trying to produce it instead. ;) Commented Jan 16, 2018 at 9:49
• @criggie If you mean do I buy one shoe in 7.5 and the other in 8, then no, that is prohibitively costly. Where available I buy half size extra shoes. However my every day walking shoes are not put under the same pressure and stresses as my cycling shoes. Commented Jan 16, 2018 at 9:52

Simple maths will show that for 50% of the population, a half-size will be closer to their “true” foot size than an integer size.

But the same maths will mean it won’t make a difference for the other 50% of the population.

We can’t tell which half of the population you’re in and whether you’d benefit.

P.s. this assumes that the sizes of human feet are a continuous rather than discrete range. This is not a trivial assumption as long-term wearing of discrete (integer) shoes may deform half-size-feet into a shape closer to integers. It also assumes the same foot size on both feet which is definitely a dangerous assumption.
