Thanks! Would make it easier to find other brands/models

I have totally reworked the browse page. You can now browse for shoes based on their ratings by foot shape, overall rating, most common fit, most common foot shape, and other parameters.

Should make the process of trying to find a shoe based on some criteria much easier. 

Check it out:

As always, if anyone has any feedback, or something isn't working quite right, please let me know.

Thanks!!!

Thanks so much for your work with this!

Interestingly, I wear a 42.5 in Sportivas  but I've never tried Five Ten. It says I should wear a size 12? I don't even wear a size 12 street shoe ...

@Adam, I wear 43.5 in La Sportiva, and 11/11.5 in Five Ten. So I expect you would need to be less than 12 in Five Ten.

@Eddie, I saw this weird combination on the size squirrel site when looking for a suggested size in a different shoe:

  • Input "Five Ten Hiangle - Men's, 11 US" - output is "La Sportiva Testarossa - Men's 43.5"
  • Input "Five Ten Hiangle - Men's, 11.5 US" - output is "La Sportiva Testarossa - Men's 43"
I went bigger for the input and the output got smaller. That doesn't seem right.

Eddie,

Thanks for all of the hard work, the site is really shaping up!

When trying to find my size, is there a way to take into account my "desired fit"? For instance, my rock shoes are for the most part sized "aggressive", but for approach shoes, I'd be looking for "normal" or "comfortable". When looking at approach shoes, it only gives me one size recommendation, using my aggressively-sized rock shoes as the starting point. How do I know what fit to expect from that recommended size in the approach shoe?

I assume it's comparing other users who have the same rock shoes, in the same size, with the same fit, who also have that approach shoe, right? Or does it also look at anyone who has that rock shoe, and that fit, and make a relative size recommendation? (Like maybe they don't wear my size, but they have the approach shoe .5 size up, so it gives me a recommendation based on that?) How does it account for people with the same shoe in a different fit?

I will look into this . But, these kind of anomalies are certainly possible. For registered users who have more than one shoe on their profile, these kind of issues should be pretty rare.

No, there isn't a way to account for desired fit. This is complicated, but it has been requested before and I will see if I can implement it somehow in the future.

It cannot tell you what fit to expect. The way the numbers work out, the fit that you should most likely expect is the most common fit for your target shoe.

The matching makes a relative size recommendation without accounting for fit. (Currently, but it would be great if it accounted for fit)

Hope that makes sense!

OK, that's what I suspected, given the way the shoes are summarized. It'd be great if if you could allow target fit for a given shoe. I know this will depend a lot on the number of people in the database, but here's a sample scenario.

I have LS Geniuses sized aggressively. I'm looking to buy LS TX2 approach shoes. If there are enough people in the database, it might be able to draw conclusions such as:
- People with aggressive geniuses and aggressive TX2's size their TX2's up .5 sizes on average from their geniuses.
- People with aggressive geniuses and normal TX2's size their TX2's up 1 size on average from their geniuses.
- etc...

Again, as more people and more shoes get loaded into the database, these recommendations become more robust. (And I assume that this is what the "accuracy" rating is in the shoe recommendation, right?)

Anyway, just some food for thought. Again, thanks for putting the work into this; it's becoming more and more useful as it evolves!

I fixed a rounding error that was causing this in some rare cases. Should lead to slightly better size predictions overall

Consider adding an article that lists all the resolers. Might pick up some more users. I started one here: mountainproject.com/forum/t…
