I think the one at Lot 10 does but I am not able to confirm it definitively( There was some promotion for customized shoes there some while back ) The ones in Singapore does.

The funny thing is different branches provide different customization . The one in Raffles City does customization for the moccasins whereas the one in Vivo City does boots?

The last time I check prices were not too expensive . The moccasins were around $300 to $400 SIN & takes 6 to 8 weeks.

A friend got a cobbler at PJ State to do that for him. Stitching was not as nice as before so beware

Not into taking vows of poverty after every purchase.
