    Hey, thanks for participating! [​IMG]

    Concerning your suggestion: I have no information about the lasts these brands use. I guess, most buyers have no information either. (Well, except Ferragamo and Bally, maybe.)

    Right now, I'd like to try with last information. But if it turns out you are right, I'll add these brands and many more.


    Can you make it optional so we can use your system for all types? Even the one pair of AEs I tried I didn't think to check the last # - I could be wrong but I think it's only SFers that even know what a last is [​IMG]

    Yes, no problem. (Well, I'd need a week or two.)

    That would, of course, mean that all shoes from a certain brand are treated the same, if there's no last information. Would you like to get a recommendation for, say, any Allen Edmonds in US9.5-D, last 'Unknown'?

    I have problems to see that this would help you spend less time on finding a fitting shoe. Maybe I'm just being used to my kind of thinking. [​IMG] Sorry, I'm just trying to understand it.

    Maybe, other members can comment on this, too?

    Opening it up without last info is a bad idea. People that come to your site and then own one of the brands listed should be expected to have a decent idea of lasts.

    One workaround is to tie the model to the last...e.g. someone can pick either the C&J Hallam or a C&J 348. While this obviously won't work for the MTO shoes, it would make it easier... particularly for brands like AE.

    Also if you can include a rudimentary price guide or recommendations based on fit and provide an affiliate link to certain stores, that could be a nice way to make ad revenue.

    Great idea in general though.

    I considered making a site like this myself.

    One thing that I think would actually be more useful would be matching up shoes that people already own.

    For example, I'm a 9.5 in most Allen Edmonds and a 10 in most Rockports.
    You could set up a matching matrix with all shoes/models and run some kind of algorithm to find out which shoes usually fit people.

    The measurements just aren't going to be precise enough IMO.

    Also, while the site itself probably would not make much money, it could be monetized by:

    1. selling some ad space (minimal money)
    2. later selling it to an online shoe retailer like zappos.com or anyone with free shipping. It could save a company like that hundreds of thousands in return shipping costs. If you build this site out you might want to think about associating serial numbers from a few of the big shops in case you want to do this later and therefore avoid a big project of matching up items later.

    Yeah, I think so, too. However, Icehawk has a point. I plan to rework the ratings form in the next week, so that last information is optional and will be added automatically. After all, the information is already in the database.

    Also if you can include a rudimentary price guide or recommendations based on fit and provide an affiliate link to certain stores, that could be a nice way to make ad revenue.

    That's a nice idea! I always wanted to provide images for the shoes, but I was worried about the traffic (and the copyright problems). But affiliates providing the images may solve that. [​IMG]

    I see want you mean... The matrix approach was also my first though.

    But the measurement approach is also more precise in the long run: The basic idea is to imaging shoes looking for 'fitting' people, instead of people looking for fitting shoes. So, let's say a shoe "tests" one hundred feet: While there will be a large variation in the measurements, the average is a good estimate for the ideal foot for these shoes.

    This way, the system can account for all kinds of systematic biases. For example, wrong measurements, fit preferences (looser vs. tighter fit), people wearing orthotics, shoe styles being different (Oxford vs. Derby vs. Chukka, etc.), leather being different (Shell vs. Calf), and lots of other things.

    But you're right: I should add the matrix approach for non-members.

    2. later selling it to an online shoe retailer like zappos.com or anyone with free shipping.

    Yeah, that would be cool! [​IMG]

    However, this is not rocket science. It's just a new approach to an old problem. As soon as one of the large online retailers gets the idea, it will take them one month to implement it themselves, I'd say. One already collects fit ratings (called "Fits true to size").

    If that happens, I'll add an export function, so everybody can move his data.

    This site is great! I just signed up. I'll be able to get my measurements as soon as I get home. (Nobody at the office has a cloth measuring tape. What's up with that???)

    I think you should have an option of sorting reccomendations by what type of shoe (i.e. Oxford, Derby, Loafer...) because the only shoe I got a reccomendation for was a loafer, which is not much help considering I wouldn't wear a loafer if you paid me. Also, some option of what part of the measaurement are you willing to give it more leeway with, such as willing to go narrower in the ball, or tighter instep and such.

    Cool idea.

    Also, I can't believe Ed hasn't commented on the "Ball Girth" measurement yet.

    ^^ That might just be due to limited data at this point.

    When there'll be enough data to provide lots of recommendations, I'll add a search/filter function.

    Also, some option of what part of the measaurement are you willing to give it more leeway with, such as willing to go narrower in the ball, or tighter instep and such.

    Noted, thanks. Right now, I think it's better it the system figures out personal preferences. [​IMG]

    OK, my data is in there. Here's what shows up right now for my recommendations: [​IMG] Not sure how accurate this data is at this time, since you're still in alpha testing. - Keith

    Not sure how accurate this data is at this time, since you're still in alpha testing.

    Well, the data is accurate insofar that I haven't found a bug in the recommendation code yet. I will check manually tomorrow. Your image is a great help.

    Concerning the accuracy for you personally... you're the only one who can judge right now.

    For me, this is a great result. Just consider the circumstances:
    • The system is designed as "dumb": It doens't know a (US) 9 is larger than as (US) 8, but treats basically every combination of last, size and width as a 'bespoke' last.
    • These recommendations are constructed from the ratings of three different guys who have no shoes in common.
    • My initial calibration of the system was just an educated guess.
    • We're up and running for a mere 4 days.

    And yet, it looks as if a (US) 9.5-D fits similar to a (UK) 8.5-F. Which is just what many SF'lers would say.

    Sorry, I think this is amazing! (I'm obviously biased, though.)

    Just imaging what's possible when the site is one year old and you have 20, 50 or even 100 people in your group... [​IMG]

    I think this is great, Claus! I'll have you know that I'm generally somewhere between a US 9E and a US 9.5D (closer to the 9.5). The results align nicely with my personal experiences. High five! - Keith
