Celtic dont return them yet! Hows the length ? if its fine , i suggest you sock trick the toe part is there enough length room for your toes or is it pushed all the way to the end of the toe box ?
I feel like my toes are pushed to the front and they start to ache. I initially thought that might be due to the pitch of the heel height.
From my other 35's i've measured, they seem to have a 9" insole. These Alti's have a 8.75" insole.
