Sizing tc pros vs mythos

I have a pair of mythos size 44. They were a great for a while but stretched nearly a full size, so are now a little sloppy, still perform ok but don't edge that great. Those of you who have had mythos and tc pros; do the tcs stretch more or less than mythos? What size do you wear in each shoe? I know a couple people who size them up a half size from mythos but looking for more input. 

Wow...Sam, now that's comparing apples and oranges. I'm a 42.5 street shoe and a 39.5 Mythos, which would corrobrate your experience. As for the TC Pros I'm in a pair of 41.5 and there will never be more than a 1/4 size stretch in those. 

My Mythos are 43.5 and my TCs are 44.5. I wear a size 12 or 46 boot and runner.

I've gotten my TC pros to stretch a full size.  It's been years since I've worn Mythos, (so long that I don't even remember my size) but I downsized TC pros a full size from my performance edging size (Muira VS) and after stretch they now fit like a glove and perform like no other shoe I've ever used.

I think I might wear my Muiras in a larger than normal size.  In the end I think it depends on what you want out of the fit.  Like John said, it can be nice to have a quiver for different uses. (high performance/tight fit, low performance/high comfort and a step or two in between)

I'm 41.5 in mythos and 43 in TC pros.  I recently tried out the scarpa techno and they are TC pros but fit better (for my feet).  Also a size 43 in techno.

Two very different shoes.  If you take the time and effort you can redo the laces on the Mythos and get them snugger as well as avoid at the crag lace break hassle.  Then you can use them on the more appropriate applications, eg. multipitch perhaps. 

It looks like 30% of users wear the TC Pro in the same size as their Mythos. 

FWIW, I'm a 41 Mythos and a 41.5 TC Pro

It depends on your feet.... I need TC two sizes larger- 43 for Mythos, 45 for TC...

If the shoe fits wear it. 

My first pair of climbing shoes was mythos in a 38, i got them resoled, and while they were gone i switched to an aggressive/sport/bouldering shoe. When i got them back, i felt like i was wearing clown shoes, that, even with socks, made 5.9 climbing feel sloppy.
So i havent tried mythos again (though should, they are so comfy), but below is some of my quiver for reference... (im a 7.5 Ladies street shoe thats a 38.5-39 in euro sizes)

Muira (womens lace): 37
TC Pros: 37.5 (my first pair was a comfy 38, which i still wear with socks for easy alpine) I found the pros stretch too, but not as much and not as quickly.
Muira (mens lace): 36.5
Katana Lace: 37.5 (but cant wear comfortably anymore due to painful pressure on my haglunds deformity)

Hi Sam, I agree with others and go about 2 sizes down in Mythos. Also, they aren't really meant for edging anyway, so that's not the best way to measure their fit. Great for long multi pitch days and cracks. Good luck!

As Max said, it really depends on what you want the shoe for.  I own sizes 36 through 38.5 and wear a 38/38.5 approach shoe.  I pick the size depending on what I am going to climb in them and how hard it is relative to my maximum ability.  I've worn my 38.5 in full on snow conditions in patagonia with thick socks.  size 38 for doing the nose in a day and not bringing approach shoes.  size 37.5 for astroman where it doesn't really require that much edging ability but a fair bit of physical climbing.  size 37 for harder multi pitch climbing where I am gonna have to get a bit serious and try hard.  size 36.5 for harder cragging and shorter hard multi pitch climbing. size 36 for full on project style redpointing where I need the best supportive edging shoe I can get, these might only get worn 10 days out of the year because they are so tight.  

And to the people that don't think these are an edging shoe or a bit "clunky" I'd recommend trying to fit them a lot tighter.  With a really tight fit I find them to be better at edging than a Muira VS.
