Eddy, you might wanna go to Cheong Aik at Desker Road to check out the apparels.
They sell pretty decent track boots labelled "Sigma".
Its about $165, good enough if ya on a budget.
For the Race Gloves, you be in for a pleasant surprise. Alphinstars used to have their gloves manufactured in PAkistan.
The Pakistanis who owns the factor makes his regular rounds to Singapore to offer Alphinestars gloves badge in Cheong Aik's own brand.
For the same thing, you pay $80. Quite brilliant actually.
