Ready for Wet Trails? Crankbrothers Seal Riding Boots

A wet-weather option for flats and clips

Crankbrothers’ Seal range pairs a waterproof upper with a high ankle wrap, offering separate options for flat and clipless pedals. The aim is to keep water and trail debris out without the bulk normally associated with winter footwear.

This MTBSA overview is adapted from the article supplied to us: MTBSA contributor’s MTBSA first ride, published on 8 October 2026. The riding observations below are his early findings, not an MTBSA hands-on test. No numerical rating was supplied.

Stamp Seal: the flat-pedal option

The Stamp version uses a HYDRO rubber outsole and a more flexible sole intended to maintain contact and feel on flat pedals. The supplied report lists 371 g per shoe in size 42, sizes 37–49, and a launch price of US$209.99 / €209.99.

Mallet Seal: the clipless option

The Mallet uses an MC1 rubber outsole and a fibre-reinforced shank for clipless riding. Reported weight is 492 g per shoe in size 42, with sizes 37–49 and a launch price of US$229.99 / €229.99. These are the overseas prices in the supplied report; South African pricing and stock have not been confirmed.

The ankle wrap is the key feature

Both versions have a wraparound collar secured with hook-and-loop material. It opens for easier entry, then closes around the ankle. Combined with suitably positioned waterproof trousers, the taller construction is intended to reduce water entering from above.

A low-absorption lining is designed to retain less water if moisture does get inside. Speed laces provide adjustment, while a TPU toe cap adds protection against impacts. Waterproof construction does not make the opening immune to water entry, so how the collar and trousers overlap still matters.

What the first rides revealed

DiGiulio reported that the Stamp Seal’s opening collar made getting the shoes on and adjusting them easier than the pull-on boots he had used. During his initial riding and trail-building sessions, the wrap stayed in place and helped keep debris out.

He also found the HYDRO rubber more convincing on pedals than earlier Crankbrothers flat-shoe compounds he had tried. That is an encouraging first impression, but his report did not yet include cold-weather testing or enough use to establish long-term durability.

Fit deserves a careful check

The reviewer described a relatively narrow forefoot and wanted a little more room. If you normally need a wide shoe, try this model with the socks you intend to ride in rather than assuming it will stretch substantially. He also identified the hook-and-loop closure as an area to watch as dirt and repeated use accumulate.

What it means for South African riders

For muddy trail days, a waterproof boot may be worth considering. The useful buying questions are straightforward: does the shape suit your feet, does it match your pedal system, and will the added coverage be comfortable in the conditions you actually ride?

For warmer, humid rides in KwaZulu-Natal, breathability remains a question to investigate before buying. The supplied first ride does not establish how these boots perform in South African summer conditions. Ask a local retailer about fit, availability and the complete rand price.

The MTBSA take

The Seal range offers a practical-looking approach to wet-weather footwear, particularly through its opening ankle wrap and choice of pedal interfaces. Early feedback on the Stamp’s grip and ease of entry is positive. Fit, hot-weather comfort and sustained waterproof performance still deserve closer scrutiny before treating this as a proven all-season shoe.
