Nano x2 difference to nano x2 sn99 ?

[BDEE]

Hola.

I am after some new training shoes for the gym and have rather wide feet.

I’ve been recommended to look at Reebok nanos.

Does anyone know the difference between the nano x2 and the nano x2 Sn99?

£20 difference and I can find the sn99 variant in the size I want but the non sn99 variant only in plain black in my size, but I can’t find any info anywhere on what the sn99 variant is or why / how it differs.

Any in the know who can enlighten me? Or even any other recommendations for good weightlifting shoes for wide feet?

Thanks
