5.10 blackwing sizing

I need a new pair of shoes for indoor climbing and these are on sale online. I have no idea what size I need. I wear a 41.5 miura and 42 in the tc pro. I also wear a 42 in the 5.10 galileo but im afraid of the 5.10 sizing. Any input would be greatly appreciated

i just got a pair too, i am excited to try them out. they generally size small, i usually wear a 10.5-11 street shoe and an 11.5 is pretty tight on me, i would generally size up at least a half size from street shoe for a tight fit

Be aware these are very foot specific, they were too asymmetric for my feet and even though my toe and heel were in line my pinky and ring toes could not handle it. I'd definitely attempt to try a pair on and size accordingly. Also these will not stretch because of the codura but should break into your foot/your foot will break in. I will say though I couldn't wear them for myself they were a great shoe and the rubber - straight stealth not onyx or c4 was fantastic. Definitely recommended if they fit.

For reference I wear

Sportiva
39.5 Miura laces
38/38.5 Cobras

5.10
8.5/41.5 Galileos
9.5 Rogues (loose for trad)

& attempted 8.5 Blackwings

Hope that helped, good luck
