What you've to take into account when buying surf shoes is the amount of grip you want. The thicker the shoe is, the warmer your feet will be but you will have much less grip in your binding, which gives you less 'board feeling'. A solution for this can be the split toe surf shoe. With this shoe, your big toe is separated from your other toes. This gives you just a little more grip and therefore more board feeling. If you want more board feeling, we recommend you take a look at our neoprene socks! A Neoprene sock also offers good protection against the cold, but they feel less stiff. For questions about the size of the surf shoe, you can always call or email us. If you order a shoe online and it isn't the right size, you can simply return it and we will send the right size to you as soon as we receive your returned goods.
